Unani and Ayurveda: Shared Roots and Differences
How Unani, with Greek and Muslim-world roots, and Ayurveda, an Indian tradition, differ in origins, ideas, treatments, evidence, safety and regulation, and what they share in modern India.

Two traditions you may see side by side
In India, Unani and Ayurveda are often grouped together. The 2020 Indian law on traditional medicine names Ashtang Ayurveda, Unani, Siddha and Sowa-Rigpa as the Indian systems of medicine. [1] A 2025 paper on India's health workforce lists Ayurveda, Yoga, Naturopathy, Unani, Siddha, Sowa Rigpa and Homoeopathy (AYUSH) as playing a significant role in Indian health care. [2] But the two traditions come from different places and explain health differently. This page compares them. It describes traditional ideas as traditional ideas, gives no self-assessment tools, and does not recommend any treatment.Where each one comes from
Unani. The word is an Arabic spelling of "Ionian," meaning Greek. Unani medicine is traced to the Greek philosopher-physician Hippocrates and his followers and was developed further in the Muslim world. [3] It is practiced today in Asia, particularly in India, Saudi Arabia, China and Japan, according to the same reference. [3]Ayurveda. NCCIH describes Ayurveda as an ancient Indian medical system based on ancient writings. [4] One research paper says it has been documented and practiced since about 1500 B.C. [5]
So the short version: Unani grew out of Greek medicine and the Muslim world, Ayurveda out of India. Both are now practiced in India. The sources we could read do not describe how the two traditions exchanged ideas over the centuries, so this page does not claim a particular historical link. We also could not read a source on Persian contributions to Unani, so we do not describe them here. See Unani Medicine and What Is Ayurveda?.
Core ideas, side by side
These are traditional frameworks. They are not biomedical mechanisms.| Unani | Ayurveda | |
|---|---|---|
| What is balanced | Four humors: blood, phlegm, yellow bile and black bile [3] | Three doshas: vata, pitta and kapha, which together set a person's constitution, called prakriti [5] |
| Where the idea comes from | The same four-fluid balance appears in Hippocratic medicine, where illness was seen as fluids falling out of balance [6] | Described in Ayurvedic writings; see the doshas as traditional concepts |
| What treatment aims to do | Aid the body's natural forces in fighting disease [3] | Keep the doshas in their balanced state [5] |
| Levels of treatment | Regimental therapy, diet, medicines and surgery [3] | Products, diet, exercise and lifestyle [4] |
| Traditional examination | Tongue, pulse, urine and stool, to judge humoral balance [3] | Described on the Ayurveda concepts page |
Both traditions use a balance idea, but they count the things being balanced differently (four versus three) and trace them to different traditions. We do not provide a humor, temperament or dosha quiz, and we do not match foods, herbs or remedies to a type.
Some Unani regimental therapies, such as purging and cupping, are named in the reference we read. [3] This page gives no instructions for them. Ask your doctor before considering any such treatment, and never try one on your own.
Medicines and quality standards
Unani medicines may be single-ingredient or multi-ingredient and may be of plant, animal, mineral and/or metal origin. [7] Ayurvedic products are mainly from plants but may include animal, metal and mineral ingredients. [4] India's Drugs and Cosmetics Act prescribes independent pharmacopeias for each system of medicine, and the Unani Pharmacopoeia of India is the regulatory compendium for Unani quality standards. [7]What research shows
Judge each treatment on its own. No trial we found compares Unani and Ayurveda head to head, so no claim that one is better is supportable.| Tradition | What we read | Label |
|---|---|---|
| Unani, blood sugar in type 2 diabetes | A 2024 systematic review found five randomized trials. Unani medications lowered fasting and after-meal blood glucose compared with control groups; the change in HbA1c was not statistically significant. [8] The authors said better study quality was needed. [8] | Promising but limited |
| Unani, broad claims | The Central Council for Research in Unani Medicines claims Unani is highly effective for many diseases, including hepatitis B, malaria and skin problems. [3] We did not find trial evidence for those claims in what we read. | Marketing claim or traditional use only until trials are found |
| Ayurveda, overall | NCCIH says few well-designed clinical trials and systematic reviews suggest Ayurvedic approaches work. [4] | Insufficient evidence as a whole; judge each intervention |
| Ayurveda, diabetes | NCCIH reports a small trial of a five-herb formula, and says inadequate study designs have not allowed firm conclusions. [4] | Insufficient evidence |
The two diabetes rows are different products tested in different ways, so do not read them as a contest. Neither is a reason to change diabetes treatment; speak to your doctor before using any herbal product, because it can affect blood sugar medicines.
Who should see a clinician first
Get conventional care first for severe, sudden or worsening symptoms, chest pain, pregnancy, children, long-term conditions or if you take prescription medicines. Tell all your health care providers about every approach you use. [10]Related pages
Unani Medicine, Siddha and Ayurveda, Traditional Healing Systems and historical use vs clinical evidence.Frequently asked questions
Is Unani medicine the same as Ayurveda?
No. Unani is traced to Greek medicine developed further in the Muslim world, and works with four humors. [3] Ayurveda is an Indian system described through three doshas. [5]
Do Unani and Ayurveda share roots?
Both are practiced in India and treated together in Indian law. [1] The sources we read do not trace a shared historical origin, so we do not claim one.
Which has better evidence, Unani or Ayurveda?
We found no head-to-head comparison. Unani has a small review of five trials for blood sugar in type 2 diabetes with promising but limited results. [8] NCCIH says few well-designed trials support Ayurvedic approaches. [4]
Are Unani and Ayurvedic medicines safe?
It depends on the product. Some Ayurvedic preparations may contain toxic amounts of lead, mercury or arsenic. [4] Unani formulations can include metal ingredients too, so ask a clinician or pharmacist. [7]
Do I need a license to practice Unani or Ayurveda?
In India, licensing runs through a national exit test and register. [1] In the United States, no state requires an Ayurvedic practitioner to be licensed. [4]

Safety and product quality
Ask a clinician or pharmacist about interactions, pregnancy and children before using either tradition's herbal products. Do not stop a prescribed medicine because of a traditional remedy.
Training and regulation
- India. One law covers both traditions, with a Board of Ayurveda and a separate Board of Unani, Siddha and Sowa-Rigpa. [1] It provides for a National Exit Test to grant a licence and a National Register of practitioners. [1]
- United States. NCCIH says no state requires an Ayurvedic practitioner to have a license. [4] Requirements for complementary practitioners differ by state and discipline. [9] The sources we read do not cover US rules for Unani practitioners.
- Elsewhere. Rules differ by country, and in many places these traditions are not regulated; check with the national or local health authority.
Being licensed is not always a guarantee of being qualified. [9] We do not list practitioners; see choosing an Ayurvedic practitioner.
