What Unani medicine is

Unani (also called Unani-tibb, or Greco-Arab medicine) is a traditional medical system rooted in ancient Greek medicine and developed further in the Muslim world. The word is an Arabic spelling of "Ionian," meaning Greek. [1] Today it is practiced mainly in South Asia, especially India. This page is the starting point for the Unani pages on this site. It describes the tradition in its own terms and then separates traditional explanation from what has been tested.

Where it comes from

A 2015 history review describes Unani as resting on Greco-Arab medicine and the teachings of Hippocrates, Galen and Arab physicians, with a long record in India. [2] Galen's works came to symbolize Greek medicine for scholars in Europe and the Middle East for some fifteen centuries. [3] A review by Unani-college authors says the system was established under Persian and Arab patronage and reached the Indian subcontinent around the middle of the 14th century. [4] The full story is on the history of Unani medicine.

Core ideas, as traditional frameworks

Unani holds that health depends on the balance of four humors (akhlat): blood, phlegm, yellow bile and black bile. [1] Each person is said to have a distinct temperament (mizaj) built from combinations of these. [4] Reviews by Unani scholars also describe six essential factors of daily life (asbab sitta darooriya), such as food, rest and activity, as the basis of prevention. [5] These are traditional explanations, not measured biology. See humors and mizaj.

Traditional practices

Reference sources describe four levels of Unani care: regimenal therapy (listed as exercise, massage, purging, cupping and others), diet-based care, medicines (mostly herbal) and surgery. [1] In Unani texts these are named Ilaj bil Tadbeer, Ilaj bil Ghida, Ilaj bil Dawa and Ilaj bil Yad. [6] Traditional examination is reported to include the tongue, pulse, urine and stool. [1] This site gives no self-assessment tools and no instructions for any treatment. Some practices, such as purging, carry real risks; see regimenal therapies.

What research shows

QuestionWhat the source foundStrength of evidence
Blood sugar in type 2 diabetesA 2024 systematic review found five randomized trials. Unani medicines lowered fasting and after-meal blood glucose versus controls, but the HbA1c change was not statistically significant. [7]Promising but limited
Unani theory (humors, temperament) as explanations of diseaseNo clinical trial testing the framework itself was found in the sources we read.Traditional use only
Overall benefit across the many conditions the tradition addressesA reference source states that robust scientific evidence of benefit is lacking. [1]Insufficient evidence

The diabetes review authors themselves said better study quality is needed. [7] Most Unani trials cannot be blinded easily, so expectation can shape results.

Who should seek conventional care first

Anyone with chest pain, severe or sudden symptoms, a new lump, pregnancy, a long-term condition such as diabetes, or who takes prescription medicines should speak with a clinician before using Unani remedies. A reference source warns that relying only on Unani medicine could delay diagnosis or treatment of serious conditions. [1] NCCIH advises telling all your health care providers about every approach you use. [12] Never stop a prescribed medicine because of a traditional remedy. Read talking with a health professional.

Frequently asked questions

Is Unani medicine the same as Greek medicine?

No. Unani grew out of Greek medicine and was developed further in the Muslim world, with its own texts, medicines and practices. [1][2]

Does Unani medicine work?

It depends on the specific treatment and condition. For blood sugar in type 2 diabetes there is limited, promising evidence from a small number of trials; for most other uses a reference source says robust evidence is lacking. [7][1]

Are Unani medicines safe?

Some are made with minerals or metals, and quality checks matter. Lead, mercury or arsenic have been a documented concern in related traditional Indian products. [8][9]

Are Unani practitioners licensed?

In India, licensing for Unani practitioners is set by national law. [10] In the United States, no state requires a license for Ayurvedic practitioners, and credentials vary by state and discipline. [9]

Can I use Unani medicine alongside my regular medicines?

Tell your clinician and pharmacist first. A reference source notes that some herbs and preparations used in Unani can be toxic or interfere with conventional treatments. [1] NCCIH advises telling all providers about everything you use. [12] Never stop a prescribed medicine on your own.

Product quality and safety
India sets quality standards through the Unani Pharmacopoeia of India and the National Formulary of Unani Medicine. Unani medicines can be made from plant, animal, mineral and metal ingredients. [8] Metals are the main concern in the wider South Asian traditions: the US National Center for Complementary and Integrative Health (NCCIH) says some Ayurvedic preparations may contain lead, mercury or arsenic in amounts that can be toxic. [9] The same caution is sensible for any traditional mineral or metal product bought online. See Unani product safety and product quality and contamination.
Practitioner training and regulation
In India, the National Commission for Indian System of Medicine Act, 2020 covers Unani with Ayurveda, Siddha and Sowa-Rigpa. It provides for a National Exit Test for a licence to practice and for a National Register. [10] In the United States, NCCIH reports that no state requires Ayurvedic practitioners to be licensed, and it notes that being licensed or certified is not always a guarantee of being qualified. [9][11] A US-specific rule for Unani practitioners was not found in the sources we read; check your state health authority. Training and Pakistan are covered on Unani in India and Pakistan.
