Ayurveda

Ayurveda is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ayurveda rather than just read about it. In short: Ayurveda ( AH-yoor-VAY-də, -⁠VEE-; IAST: āyurveda) is an alternative medicine system with historical roots in the Indian subcontinent. It is heavily practised throughout India and Nepal, where as much as 80% of the population report using Ayurveda.

Key takeaways

Ayurveda belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ayurveda to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ayurveda from memory before moving on to harder problems.

Reference excerpt

Ayurveda ( AH-yoor-VAY-də, -⁠VEE-; IAST: āyurveda) is an alternative medicine system with historical roots in the Indian subcontinent. It is heavily practised throughout India and Nepal, where as much as 80% of the population report using Ayurveda. Ayurveda has been adapted for Western consumption, notably by Baba Hari Dass in the 1970s and Maharishi Ayurveda in the 1980s. The theory and practice of Ayurveda are pseudoscientific, and many Ayurvedic preparations, particularly in the rasashastra tradition, contain toxic levels of lead, mercury, and arsenic. There is no evidence that cancer can be treated or cured through Ayurveda. Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils. Early Ayurvedic preparations were almost entirely based on complex herbal compounds based on the materia medica of South Asia. Minerals and other metal substances began to enter the traditional pharmacopoeia more pervasively after the eleventh century, under the influence of early Indian alchemy or rasashastra. Ancient Ayurveda texts also taught surgical techniques, including rhinoplasty, lithotomy, sutures, cataract surgery, and the extraction of foreign objects. Historical evidence for Ayurvedic terminology and concepts appear in the Buddhist Canon from the middle of the first millennium BCE onwards. The main classical Ayurveda texts are datable in their present form to the first centuries CE. Like many texts from classical antiquity, these texts begin with accounts of the transmission of medical knowledge from the gods to sages and then to human physicians. Printed editions of the Sushruta Samhita (Sushruta's Compendium), frame the work as the teachings of Dhanvantari, the Hindu deity of Ayurveda, incarnated as King Divodāsa of Varanasi, to a group of physicians, including Sushruta. The oldest manuscripts of the work, however, omit this frame, ascribing the work directly to King Divodāsa. In Ayurveda texts, dosha balance is emphasised, and suppressing natural urges is considered unhealthy and claimed to lead to illness. Ayurveda treatises describe three elemental doshas: vāta, pitta and kapha, and state that balance (Skt. sāmyatva) of the doshas results in health, while imbalance (viṣamatva) results in disease. Ayurveda treatises divide medicine into eight canonical components. Ayurveda practitioners had developed various medicinal preparations and surgical procedures from at least the beginning of the common era.

Etymology The term āyurveda (Sanskrit: आयुर्वेद) is composed of two words, āyus, आयुस्, "life" or "longevity", and veda, वेद, "knowledge", translated as "knowledge of longevity" or "knowledge of life and longevity".

Eight components

The earliest classical Sanskrit works on Ayurveda describe medicine as being divided into eight components (Skt. aṅga). This characterization of the physician's art, "the medicine that has eight components" (Sanskrit: चिकित्सायामष्टाङ्गायाम्, romanized: cikitsāyām aṣṭāṅgāyāṃ), is first found in the Sanskrit epic the Mahābhārata, c. 4th century BCE. The components are:

Kāyachikitsā: general medicine, medicine of the body Kaumāra-bhṛtya (Pediatrics): Discussions about prenatal and postnatal care of baby and mother; methods of conception; choosing the child's sex, intelligence, and constitution; childhood diseases; and midwifery Śalyatantra: surgical techniques and the extraction of foreign objects Śhālākyatantra: treatment of ailments affecting openings or cavities in the upper body: ears, eyes, nose, mouth, etc. Bhūtavidyā: pacification of possessing spirits, and the people whose minds are affected by such possession Agadatantra/Vishagara-vairodh Tantra (Toxicology): includes epidemics; toxins in animals, vegetables and minerals; and keys for recognizing those anomalies and their antidotes Rasāyantantra: rejuvenation and tonics for increasing lifespan, intellect and strength Vājīkaraṇatantra: aphrodisiacs; treatments for increasing the volume and viability of semen and sexual pleasure; infertility problems. Note, however, that the chapter-divisions of the major ancient encyclopedias of Ayurveda do not follow these divisions.

Principles and terminology

The central philosophical ideas of Ayurveda show parallels with Samkhya and Vaisheshika philosophies, as well as with Buddhism and Jainism. Moderation is emphasized, and suppressing natural urges is considered unhealthy and claimed to lead to illness. For example, to suppress sneezing is said to potentially give rise to shoulder pain. However, people are also cautioned to stay within the limits of reasonable balance and measure when following nature's urges. For example, emphasis is placed on moderation of food intake, sleep, and sexual intercourse.

Worked examples

Example 1 — a first encounter with Ayurveda

Start with the simplest possible case. Write down what Ayurveda claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ayurveda before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ayurveda ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ayurveda

In research: Ayurveda appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ayurveda in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ayurveda is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ancient Indian medicine, Ayurveda, History of ancient medicine, so understanding it makes those chapters shorter.
In everyday life: Look for Ayurveda outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Ayurveda in simple terms?

Why does Ayurveda matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
