Ayurveda

Lore & Background

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 preparations were almost entirely based on complex herbal compounds, but minerals and metal substances entered the 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 appears 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. 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 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; however, the oldest manuscripts omit this frame, ascribing the work directly to King Divodāsa.

In Ayurveda texts, dosha balance is emphasized, and suppressing natural urges is considered unhealthy. Three elemental doshas are described: vāta, pitta, and kapha, and balance of the doshas is said to result in health, while imbalance results in disease. Ayurveda treatises divide medicine into eight canonical components, including general medicine, pediatrics, surgical techniques, treatment of upper body ailments, pacification of possessing spirits, toxicology, rejuvenation, and aphrodisiacs.

Reader's Guide

Ayurveda remains a widely practiced system of alternative medicine, particularly in India and Nepal, where up to 80% of the population report using it. Its theory and practice are considered pseudoscientific, and many Ayurvedic preparations, especially 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. The system's central philosophical ideas show parallels with Samkhya and Vaisheshika philosophies, as well as with Buddhism and Jainism. Contemporary critics assert that the doshas are not real but a fictional concept. Despite these criticisms, Ayurveda has been adapted for Western consumption and continues to influence holistic health practices. Its historical significance lies in its ancient texts, surgical techniques, and the development of complex herbal and metal-based preparations over more than two millennia.

The BAMS Degree and Its Dual Curriculum

The Bachelor of Ayurvedic Medicine and Surgery stands as a professional qualification dedicated to the study and practice of Ayurveda, a system of alternative medicine whose theoretical foundations and clinical applications are widely regarded as pseudoscientific. The degree is available across four South Asian nations—India, Nepal, Bangladesh, and Sri Lanka—each of which maintains its own institutional framework for training practitioners. In India, the syllabus weaves together a substantial body of classical Ayurvedic disciplines, including Rachana Sharira, Kriya Sharira, Dravyuaguna, Svasthavritta and Yoga, Roga Nidana and Vikriti Vijnana, Kāyachikitsā, Kaumara Bhritya, Prasuti Tantra, Shalya Tantra, and Shalakya Tantra. Alongside these traditional subjects, students must also engage with modern medical sciences such as human anatomy, physiology, pathology, pharmacology, toxicology, forensic medicine, and specialties ranging from ophthalmology to gynecology and surgery. The curriculum further demands engagement with ancient and medieval Ayurvedic texts, occasionally studied in the original Sanskrit. Prominent Indian institutions offering the degree include the National Institute of Ayurveda and the All India Institute of Ayurveda in Delhi.

Legal Boundaries: Who May Prescribe What

India's regulatory landscape for AYUSH practitioners rests on a legal principle: a doctor may practice exclusively within the system of medicine in which they hold qualification and registration. The Supreme Court of India reinforced this boundary in its 1998 judgment in Dr. Mukhtiar Chand & Others v. State of Punjab, ruling that AYUSH practitioners cannot prescribe allopathic medicines. Yet the court carved out an exception—state governments retain the authority to issue notifications permitting limited prescription of specified modern medicines. In practice, this has produced a patchwork of state-level permissions. More than thirteen states, including Assam, Tamil Nadu, Maharashtra, Himachal Pradesh, and Andhra Pradesh, now allow BAMS graduates to prescribe allopathic drugs. In Maharashtra, following protests by BAMS doctors, practitioners gained the right to prescribe modern medicines and perform minor surgical procedures. Karnataka takes a narrower approach, permitting BAMS doctors in rural primary health centres to administer modern-medicine treatment strictly in emergencies. Kerala, by contrast, has maintained a restrictive stance; during the COVID-19 pandemic its government barred AYUSH practitioners from prescribing modern drugs for the virus, confining their role to preventive and immunity-related care. The Kerala High Court, while upholding these restrictions, acknowledged that allopathic prescriptions remain permissible in life-threatening emergencies.

WHO Perspectives and Global Standing

The World Health Organization has addressed Ayurveda's place in global health on two notable occasions. A 2001 report confirmed that the system was widely practiced across India, Nepal, Bangladesh, and Sri Lanka—the same four nations that offer the BAMS degree. However, the WHO noted that Ayurveda was generally not integrated into the national health systems of countries outside the Indian subcontinent, underscoring its regional rather than universal character. A subsequent 2020 WHO report acknowledged India's long history of combining allopathic and traditional medicine systems, including through medical education. Yet the organization drew a sharp structural distinction, describing AYUSH and conventional medical systems as separate and parallel at the levels of governance, organisation, education, and service delivery. This characterization highlights that, despite coexisting within the same national framework, the two systems operate in distinct institutional silos. It is also worth noting that Ayurveda is broadly classified as a form of alternative medicine, with its underlying theory and practice widely regarded as pseudoscientific. The Central Council of Indian Medicine serves as the apex regulatory body in India, overseeing both the education and practice of BAMS-qualified doctors.

Postgraduate Pathways and Educational Gaps

Beyond the BAMS degree, India's academic ecosystem offers a range of advanced qualifications for Ayurveda graduates. Students may pursue a master's degree in the form of MD (Ayurveda) or MS (Ayurveda), progress to a PhD, or earn clinical doctorate degrees in traditional and complementary medicine at the university level. Career opportunities extend into research, hospital and healthcare administration, and health supervision, suggesting a broad professional landscape for qualified practitioners. However, the quality of foundational training has drawn scrutiny. A 2009 nationwide survey conducted by researchers at Banaras Hindu University, which included a total of 1,022 students and teachers of Ayurveda, revealed that BAMS graduates generally lack the required exposure to essential clinical skills. A companion paper derived from the same study identified multiple global challenges confronting the Ayurveda education sector. These findings raise significant questions about whether the dual curriculum—spanning classical Sanskrit texts and modern medical sciences—equips graduates with the practical competencies needed for safe patient care, particularly in a system whose theoretical foundations are widely considered pseudoscientific.
