Why This Glossary Exists
When you visit an Ayurvedic practitioner for the first time, you will hear terms like Agni, Ama, Dosha, and Prakriti. These are not decorative jargon — they are precise clinical concepts with specific meanings that have been refined over thousands of years. Understanding them helps you understand why your practitioner recommends what they do. This glossary covers the terms you are most likely to encounter, organised alphabetically. Where a term connects to a deeper article on this site, we have linked to it so you can explore further.
A
- Abhyanga
- Oil massage using warm, herb-infused oils selected for your constitution. Abhyanga is not a spa treatment — it is a therapeutic practice described in the Charaka Samhita as part of Dinacharya (daily routine). The oil nourishes skin, calms Vata dosha, supports circulation, and helps the body release accumulated tension. The choice of oil depends on your Prakriti and the season.
- Agni
- Digestive fire — the single most important concept in Ayurvedic clinical practice. Agni is not just stomach acid. It is the body’s entire capacity to digest food, absorb nutrients, and transform what you eat into tissue. When Agni is strong, digestion is complete and no waste accumulates. When Agni weakens, undigested material (Ama) builds up and becomes the root of most chronic conditions. Charaka Samhita states: “The span of life, health, immunity, energy, metabolism — all depend on Agni.” There are 13 types of Agni described in the classical texts, governing different levels of metabolism. Read the full article on Agni and Digestion.
- Ahara
- Food and diet. In Ayurveda, Ahara is considered one of the three pillars of life (Trayopastambha), alongside sleep (Nidra) and managed conduct (Brahmacharya). Food is not categorised by calories or macronutrients but by its taste (Rasa), qualities (Guna), post-digestive effect (Vipaka), and specific potency (Prabhava). The same food can be medicine for one person and harmful for another, depending on their constitution and current state.
- Ama
- The silent troublemaker behind most chronic conditions. Ama is the toxic, sticky residue that forms when Agni is too weak to fully digest food. Picture it this way: a well-burning fire leaves only fine ash, but a smouldering one leaves thick, tar-like residue. That residue is Ama. It is heavy, cloudy, and foul-smelling — the exact opposite of healthy tissue. Ama first accumulates in the digestive tract, then hitches a ride through the Srotas (channels) and lodges wherever the body is weakest, laying the groundwork for disease. A coated tongue in the morning is one visible sign. The concept maps remarkably well onto modern research into gut permeability, endotoxins, and chronic low-grade inflammation. Much of Ayurvedic treatment is fundamentally about two things: stopping Ama production (by strengthening Agni) and clearing the Ama that has already accumulated. Read the full article on Understanding Ama. Also see: Agni and Digestion.
- Anupana (అనుపానం)
- The carrier substance taken along with a medicine to enhance absorption and direct it to the target tissue. Common anupanas include warm water (most universal), honey (for Kapha conditions — scraping, drying), ghee (for Vata and Pitta conditions — nourishing, cooling), and warm milk (for Shukra/reproductive tissue nourishment). The choice of Anupana is not arbitrary — it is selected based on the patient’s constitution, the condition being addressed, and the nature of the medicine itself. Charaka describes Anupana as having the power to carry the medicine’s effect to specific tissues (dhatus) and channels (srotas). Taking a medicine with the wrong vehicle can reduce its effectiveness or create unwanted effects. See the Understanding Your Prescription guide for practical guidance on carriers.
- Ashtanga (Eight Branches)
- The eight specialised branches of Ayurvedic medicine: Kaya Chikitsa (internal medicine), Shalya Tantra (surgery), Shalakya Tantra (ENT and ophthalmology), Kaumara Bhritya (paediatrics), Agada Tantra (toxicology), Bhuta Vidya (psychiatry), Rasayana (rejuvenation), and Vajikarana (reproductive medicine). These were established over 2,500 years ago — meaning Ayurveda had medical specialisation millennia before modern medicine developed equivalent fields. Explore the eight branches in the History article.
B
- Bala (Three Types of Strength)
- Strength in Ayurveda is not a single number on a scale — it comes in three distinct types, and your practitioner assesses all three before planning treatment. Sahaja Bala is the strength you are born with, wired into your constitution (Prakriti) and unchangeable. Kalaja Bala is the strength that fluctuates with time — your age, the season, and even the time of day affect it (you are naturally stronger in youth and in winter, weaker in old age and summer). Yuktikrita Bala is the only type you can actively build: through proper diet, exercise, Rasayana therapy, and lifestyle adjustments. A practitioner who understands your Bala profile will never over-treat or under-treat — they calibrate the intensity of Panchakarma, the strength of formulations, and the pace of recovery to match what your body can actually handle.
- Basti
- One of the five Panchakarma procedures — a medicated enema therapy considered the most important of all Panchakarma actions. Basti directly addresses Vata dosha (which resides primarily in the colon) and is used for a wide range of chronic conditions. Charaka calls Basti “half of the entire treatment” (Ardha Chikitsa) because of its broad clinical reach. There are multiple types: Anuvasana (oil-based) and Niruha (decoction-based), each selected based on the condition and constitution.
- Bheshaja Kala (భేషజ కాలం)
- The timing of medicine administration — one of the most important factors in Ayurvedic pharmacology. Charaka describes specific timings: before food (Abhakta — for downward-moving conditions), after food (Adhobhakta — for upper body conditions), with food (Sagrasa — for conditions of the middle body), between meals (Antarabhakta — for heart/digestive conditions), and at bedtime (Nishi — for conditions above the shoulders or Vata conditions that worsen at night). The principle is that timing determines which Agni and which Srotas the medicine encounters first.
- Brihat Trayi
- The “Great Triad” — the three foundational texts of Ayurveda: Charaka Samhita (internal medicine, circa 300 BCE), Sushruta Samhita (surgery, circa 600 BCE), and Ashtanga Hridaya by Vagbhata (synthesis, circa 7th century CE). Together they form the most comprehensive medical literature the ancient world produced. All three are still studied and clinically applied today. Read about the Brihat Trayi in the History article.
D
- Dhatu (Seven Tissues)
- The seven tissue layers of the body, nourished sequentially by Agni. In order: Rasa (plasma/lymph), Rakta (blood), Mamsa (muscle), Meda (fat/adipose), Asthi (bone), Majja (marrow/nerve), and Shukra/Artava (reproductive tissue). Each Dhatu is formed from the previous one — so weak Rasa Dhatu eventually affects all downstream tissues. This sequential nourishment model explains why Ayurvedic treatment takes time: the body rebuilds layer by layer, not all at once. It also explains why poor digestion (weak Agni) eventually affects the entire body.
- Dinacharya
- The Ayurvedic daily routine — a structured sequence of practices from waking to sleeping that maintains health by aligning the body with natural rhythms. Includes tongue scraping, oil pulling, self-massage, exercise, meal timing, and sleep hygiene. The 2017 Nobel Prize in Medicine (for circadian rhythm research) validated the core principle behind Dinacharya: that the body has internal clocks governing digestion, repair, and hormone release. Read the full Dinacharya article.
- Dosha
- The three fundamental bio-energies that govern all physiological and psychological functions: Vata (air + space — movement, nerve impulses, breathing, elimination), Pitta (fire + water — digestion, metabolism, body temperature, intellect), and Kapha (earth + water — structure, lubrication, immunity, stability). Every person has all three Doshas, but in a unique ratio that defines their constitution (Prakriti). Disease occurs when Doshas move out of their natural balance (Vikriti). Ayurvedic treatment aims to restore each Dosha to its constitutional baseline. Learn about your Dosha balance in the Prakriti article.
Did You Know?
Sushruta’s definition of Swasthya (health) requires seven conditions to be present simultaneously: balanced Doshas, properly functioning Agni, well-formed Dhatus, proper Mala elimination, happy senses, happy mind, and happy soul. The WHO’s 1948 definition of health — “physical, mental, and social well-being” — covers three dimensions. Sushruta’s covers seven, and was written roughly 2,600 years earlier. When people say Ayurveda is “holistic,” this is not a marketing word. It is a measurable difference in diagnostic scope.
G
- Guna (Qualities)
- The twenty fundamental qualities (Vimshati Guna) used to describe everything in Ayurveda — foods, herbs, seasons, body states, and treatments. They exist in ten opposing pairs: heavy/light, cold/hot, oily/dry, slow/sharp, stable/mobile, soft/hard, clear/cloudy, smooth/rough, subtle/gross, solid/liquid. Treatment follows a simple principle: “like increases like, and opposites balance.” If a condition is cold and dry (like Vata imbalance), the treatment uses warm and oily qualities. This is why two patients with the same symptoms may receive different prescriptions.
H
- Hridaya
- The heart — but not only the physical organ. In Ayurveda, Hridaya is the seat of consciousness, emotion, Ojas, and the mind (Manas). Charaka and Sushruta both describe Hridaya as one of the three Marma points (vital centres) whose injury is immediately life-threatening. But Hridaya’s clinical significance goes further: it is where Sadhaka Pitta resides — the sub-dosha responsible for emotional processing, courage, and the ability to turn knowledge into understanding. When a practitioner says stress is “affecting your Hridaya,” they are not being poetic. They mean that the functional centre governing both cardiac rhythm and emotional equilibrium is disturbed — a concept that modern psychocardiology, studying the heart-brain connection, is now catching up with.
K
- Kapha
- The Dosha formed from earth and water elements. Kapha governs structure, stability, lubrication, and immunity. People with a Kapha-dominant constitution tend to have sturdy builds, calm temperaments, strong endurance, and smooth skin. When Kapha increases beyond its natural level, it can manifest as congestion, weight gain, lethargy, fluid retention, and attachment. Kapha is strongest in childhood and in spring (Vasanta Ritu). Learn more in the Prakriti article.
- Kashayam
- A water-based herbal decoction — one of the most common Ayurvedic preparation types. Herbs are boiled in water until reduced to a concentrated liquid. Kashayam is typically prescribed for conditions where quick absorption and strong action are needed. Other common preparation types include Churnam (powders), Tailam (medicated oils), Lehyam (herbal jams), Ghritam (medicated ghee), Arishtam/Asavam (fermented preparations), and Gulika (tablets).
- Kala (Time)
- Time as a therapeutic factor — one of the most underappreciated concepts in Ayurveda and one that separates a skilled practitioner from a textbook one. Kala operates on multiple scales simultaneously. At the micro level, there is the right time of day to take a formulation (before meals, after meals, at bedtime — each produces different effects). At the seasonal level, certain treatments are only effective during specific Ritus (seasons). At the disease level, Kala determines whether a condition is acute (Ashukari) or chronic (Chirukari), which entirely changes the treatment approach. And at the life-stage level, what works for a young person may be inappropriate for an elderly one. Charaka even describes “Kala-bala” — the strength the body draws from favourable time periods. When your practitioner specifies exact timing for each formulation, this is the principle at work.
M
- Mala
- Waste products of the body. The three primary Malas are Purisha (stool), Mutra (urine), and Sveda (sweat). Healthy elimination is considered essential to health in Ayurveda — as important as proper digestion. Your practitioner will ask about bowel regularity, urine colour, and sweating patterns because these reveal the state of Agni and Dosha balance. Incomplete elimination allows Ama to accumulate.
N
- Nadi Pariksha
- Pulse diagnosis — the primary diagnostic technique in Ayurvedic clinical practice. The practitioner reads three positions on the radial artery (at the wrist) using the index, middle, and ring fingers, each corresponding to Vata, Pitta, and Kapha respectively. The quality, speed, rhythm, and depth of the pulse reveal the state of each Dosha, the strength of Agni, the presence of Ama, and the condition of specific organs. This requires years of training and is considered both a science and an art.
- Nidra
- Sleep — one of the three pillars of life (Trayopastambha). Ayurveda considers proper sleep as important as proper diet. Charaka Samhita describes sleep as emerging from Tamas guna (the quality of heaviness and rest) and lists specific consequences of inadequate sleep: weakened immunity, impaired digestion, pain, and mental fog. Sleep timing also matters — sleeping before 10 PM (during the Kapha period) produces deeper rest than sleeping after midnight. Read the full article on Ayurvedic sleep.
O
- Ojas
- The finest essence produced when all seven Dhatus are properly nourished. Ojas represents vitality, immunity, and the glow of health. It is not a substance you can isolate under a microscope — it is a functional concept describing the body’s overall resilience. When Ojas is strong, you resist illness, heal quickly, and feel vital. When Ojas depletes (through chronic stress, poor diet, overwork, or illness), immunity drops and recovery slows. Rasayana therapy is specifically designed to rebuild Ojas.
P
- Panchakarma
- The five purification actions — Ayurveda’s classical detoxification system. The five procedures are: Vamana (therapeutic emesis), Virechana (therapeutic purgation), Basti (medicated enema), Nasya (nasal administration), and Raktamokshana (bloodletting). Panchakarma is not a weekend cleanse — it is a medically supervised, multi-week process with three phases: Purvakarma (preparation, including oil massage and sweating), Pradhanakarma (the main procedure), and Paschatkarma (rebuilding with diet and Rasayana). Not everyone needs Panchakarma, and the specific procedures are selected based on individual assessment. Read the full Panchakarma article.
- Pathya / Apathya
- What is suitable (Pathya) and what is unsuitable (Apathya) for a specific person in a specific condition. This is the Ayurvedic approach to diet and lifestyle during treatment. Rather than a universal “healthy diet,” Pathya is personalised — what is Pathya for a Vata person may be Apathya for a Kapha person. Your practitioner will give you specific Pathya-Apathya guidance as part of your consultation. See the Diet & Lifestyle guide for practical details.
- Pitta
- The Dosha formed from fire and water elements. Pitta governs digestion, metabolism, body temperature, skin colour, intellect, and courage. People with a Pitta-dominant constitution tend to have medium builds, sharp intellect, strong appetite, warm body temperature, and decisive personalities. When Pitta increases, it can manifest as acidity, inflammation, skin rashes, irritability, and excessive heat. Pitta is strongest in the middle years of life and in summer (Grishma Ritu). Learn more in the Prakriti article.
- Prakriti
- Your birth constitution — the unique Dosha ratio you were born with, determined at conception and unchangeable throughout life. Prakriti is the baseline your body always tries to return to. It determines your physical build, temperament, digestion pattern, sleep needs, disease susceptibility, and response to treatment. Two patients with the same symptoms but different Prakriti may receive entirely different prescriptions. Understanding Prakriti is the foundation of personalised Ayurvedic care. Genomic studies published in the Journal of Translational Medicine have found statistically significant correlations between Prakriti types and gene expression patterns. Read the full Prakriti article.
R
- Rasa (Taste)
- The six tastes recognised in Ayurveda: Madhura (sweet), Amla (sour), Lavana (salty), Katu (pungent), Tikta (bitter), and Kashaya (astringent). Each taste has specific effects on the Doshas. Sweet, sour, and salty increase Kapha and decrease Vata. Pungent, bitter, and astringent increase Vata and decrease Kapha. A balanced meal should ideally contain all six tastes. This is the principle behind traditional preparations like Ugadi Pachadi, which contains all six in a single dish.
- Rasayana
- The science of rejuvenation — one of the eight branches of Ayurveda. Rasayana is not anti-ageing in the cosmetic sense. It is a systematic approach to rebuilding tissue quality (Dhatu Sara), strengthening immunity (Ojas), and extending healthy lifespan. Rasayana formulations nourish the tissues layer by layer, starting from Rasa Dhatu (plasma) and working through to Shukra Dhatu (reproductive tissue). The approach is always constitution-specific. Read the full Rasayana article.
- Ritucharya
- Seasonal routine — the Ayurvedic practice of adjusting diet, activity, and lifestyle with the six seasons (Shishira, Vasanta, Grishma, Varsha, Sharad, Hemanta). The reasoning is that Doshas naturally fluctuate with seasons: Vata accumulates in summer and aggravates in the monsoon; Pitta accumulates in the monsoon and aggravates in autumn; Kapha accumulates in winter and aggravates in spring. Ritucharya prescribes specific adjustments to prevent these seasonal imbalances before they cause illness. Read the full Ritucharya article.
S
- Samprapti (Shat Kriya Kala)
- The pathogenesis of disease — the six-stage process (Shat Kriya Kala) by which an imbalanced Dosha progresses from mild accumulation to full-blown disease. The six stages are: Sanchaya (accumulation — the Dosha quietly builds up in its home site), Prakopa (aggravation — it starts to “boil over”), Prasara (spread — it overflows into the circulation), Sthana Samshraya (localisation — it lodges in a vulnerable tissue), Vyakti (manifestation — recognisable symptoms finally appear), and Bheda (complications — structural damage sets in). Here is the critical insight: Ayurveda’s diagnostic tools — pulse reading, tongue examination, constitutional assessment — can detect imbalances at stages 1–3, before any symptoms manifest. Modern diagnostic imaging and blood work typically catches disease at stages 5–6. This means Ayurveda has a four-stage head start on intervention — which is why the tradition emphasises prevention so heavily.
- Satmya (Habituation)
- What the body has become accustomed to through long use — and this concept explains something that puzzles many people: why a food or practice that is “generally healthy” can cause problems for a specific person, or why something “generally unhealthy” seems to suit someone just fine. If your family has consumed curd daily for generations, your body has adapted to it — curd is Satmya for you. Abruptly removing it can cause more harm than good, even if a textbook says otherwise. Conversely, introducing an unfamiliar food (even a nutritious one) too quickly can disrupt digestion. A skilled practitioner never makes sudden, dramatic diet changes. They move gradually from your current Satmya toward optimal choices — because the body adapts step by step, not overnight.
- Sneha (Oleation)
- The therapeutic use of oils and fats — both externally (as massage) and internally (as medicated ghee or oils taken by mouth). Sneha is the essential first step of Purvakarma, the preparation phase before Panchakarma. The logic is elegant: Ama and accumulated Doshas are lodged deep in tissues. Oil, being lipophilic, penetrates into those tissues, loosens what is stuck, and draws toxins toward the digestive tract where they can be eliminated. Without proper Sneha, the main Panchakarma procedures are far less effective — like trying to wash a greasy pot with water alone. The duration and type of Sneha are carefully calibrated to the individual. Read about Sneha’s role in Panchakarma.
- Srotas
- The channels or pathways through which substances flow in the body. There are 13 main Srotas described in Ayurveda, carrying nutrients, waste, breath, water, and tissue-forming substances. When Srotas are clear, flow is unimpeded and health is maintained. When Srotas become blocked (by Ama, excess Dosha, or improper diet), the blocked area becomes the site of disease. Treatment often involves clearing the obstructed Srotas and restoring proper flow.
- Svedana (Sudation)
- Therapeutic sweating — the second step of Purvakarma (preparation for Panchakarma), always performed after Sneha (oleation). If Sneha loosens toxins from the tissues, Svedana uses heat to open the Srotas (channels) and move those loosened toxins toward the digestive tract for elimination. Think of it as softening hardened wax with warmth so it can flow out. Svedana is not just sitting in a steam box — Charaka describes 13 different methods, ranging from steam baths and warm poultices to specific herbal fumigation, each selected based on the condition and constitution. Some conditions actually contraindicate Svedana entirely (certain Pitta disorders, for example), which is why it is always practitioner-directed. Learn about Svedana in the Panchakarma article.
- Swasthya
- Health — literally “established in oneself” (Swa = self, Sthya = established). This is Ayurveda’s definition of health, and it is more demanding than the mere absence of disease. Sushruta Samhita defines Swasthya as: balanced Doshas, properly functioning Agni, well-formed Dhatus, proper elimination of Malas, happy senses (Prasanna Indriya), happy mind (Prasanna Manas), and happy soul (Prasanna Atma). All seven conditions must be present simultaneously for a person to be truly healthy.
Did You Know?
The Shat Kriya Kala (six stages of disease pathogenesis) means Ayurveda can detect four stages of disease progression before modern diagnostic tools typically can. Stages 1–4 (Sanchaya, Prakopa, Prasara, Sthana Samshraya) produce subtle changes in pulse quality, tongue coating, digestion, and energy — all detectable by a trained practitioner — but no lab abnormalities or imaging findings. Modern medicine usually enters the picture at stage 5 (Vyakti), when symptoms are unmistakable and blood work finally shows something. This is not a criticism of modern medicine — it is a reframing of what “preventive medicine” actually means. True prevention is intervening at stage 1, not screening for disease at stage 5.
T
- Trayopastambha (Three Pillars)
- The three pillars of life that sustain health: Ahara (food), Nidra (sleep), and Brahmacharya (managed conduct/energy conservation). Charaka Samhita states that when these three are properly maintained, the body remains strong throughout life. These are not suggestions — they are the load-bearing pillars. If any one collapses, the body’s health deteriorates regardless of what medicines are taken. This is why Ayurvedic treatment always addresses diet, sleep, and lifestyle alongside any formulations.
U
- Upashaya (Therapeutic Trial)
- A diagnostic technique where the practitioner uses a small therapeutic intervention — a specific food, activity, or mild formulation — to confirm or rule out a diagnosis. If the intervention brings relief, the suspected imbalance is confirmed. If it worsens or has no effect, the practitioner reassesses. Upashaya is essentially the Ayurvedic version of a “therapeutic trial,” a concept that modern medicine also uses but rarely credits to its ancient origins. What makes Upashaya remarkable is its sophistication: Charaka describes not just “did it help?” but a matrix of responses (Hetu-viparita, Vyadhi-viparita, Hetu-Vyadhi-viparita) that narrow the diagnosis with each iteration. It turns treatment itself into a diagnostic instrument.
V
- Vata
- The Dosha formed from air and space elements. Vata governs all movement in the body: nerve impulses, breathing, blood circulation, muscle movement, elimination, and the movement of thoughts. People with a Vata-dominant constitution tend to have light, thin frames, quick minds, creativity, and variable energy. When Vata increases, it can manifest as anxiety, dry skin, constipation, joint pain, insomnia, and scattered thinking. Vata is strongest in old age and in the monsoon/autumn seasons. Vata is considered the “king of Doshas” because it drives the other two — Pitta and Kapha cannot move without Vata. Learn more in the Prakriti article.
- Vihara
- Lifestyle and daily conduct — encompassing exercise, sleep, sexual activity, seasonal behaviour, and mental habits. Together with Ahara (diet) and Aushadha (medicine), Vihara forms the three components of Ayurvedic treatment. In many chronic conditions, adjusting Vihara produces more lasting results than medicine alone. Your practitioner’s lifestyle recommendations are not optional add-ons — they are a core part of treatment. See the Diet & Lifestyle guide.
- Vikriti
- Your current state of Dosha imbalance — as opposed to your birth constitution (Prakriti). If Prakriti is your default setting, Vikriti is how far you have drifted from it. The gap between Prakriti and Vikriti tells the practitioner exactly what has gone out of balance and guides the treatment plan. The goal of Ayurvedic treatment is to bring Vikriti back in line with Prakriti. Understand Prakriti vs Vikriti in the full article.
- Vipaka
- The post-digestive effect of a substance — what remains after Agni has processed it. While a food or herb may have one taste (Rasa) on the tongue, its effect after digestion (Vipaka) may be different. Sweet and salty tastes generally produce a sweet Vipaka (nourishing, building). Sour taste produces a sour Vipaka. Pungent, bitter, and astringent tastes produce a pungent Vipaka (drying, reducing). Understanding Vipaka explains why some foods taste pleasant but cause problems later, and why some bitter medicines have deeply nourishing long-term effects.
- Viruddha Ahara (Incompatible Foods)
- Food combinations that, individually, may be perfectly fine but together produce toxic effects in the body. This is not folk wisdom or random dietary rules — Charaka Samhita dedicates an entire chapter to Viruddha Ahara and lists 18 categories of incompatibility. Some are based on qualities (mixing hot and cold potency foods), some on processing (heating honey), some on timing (eating heavy food when Agni is low), and some on constitution (a Kapha person eating Kapha-increasing combinations). The most commonly cited example — fish with milk — is considered Viruddha because they have opposite Vipaka effects that confuse Agni. Modern food science is beginning to explore similar territory through research on food synergies and anti-nutrient interactions, though the field is still catching up to the specificity of Charaka’s classifications.
A Living Vocabulary
The terms in this glossary are not historical curiosities. They are the working vocabulary of a medical system practiced continuously for over 3,000 years. Concepts like Agni, Dosha, and Dhatu are used in clinical settings today by practitioners who assess, diagnose, and prescribe using the same framework the classical texts established.
Modern research continues to find convergence between Ayurvedic concepts and contemporary science. The gut-brain axis parallels the Agni-Manas connection. Circadian medicine validates Dinacharya. Genomic studies correlate with Prakriti classification. This glossary is a starting point — each term opens into a deeper understanding that the articles on this site explore further.
This glossary is for educational purposes only and does not constitute medical advice. Ayurvedic terms describe a traditional framework for understanding health. For personalised guidance, consult a qualified practitioner. Always inform your healthcare providers about any traditional approaches you are considering.
