Madhuka (Mahua Flower): Identity, Traditional Uses & Evidence

TL;DR

"Madhuka" names two different Ayurvedic drugs: mahua flower (Madhuca longifolia) and licorice root (Glycyrrhiza glabra). This article covers mahua flower, traditionally used for cough, fever, and debility: and widely eaten as everyday food in rural India. A comprehensive 2025 review found no human clinical trials of the flower; all pharmacological evidence is preclinical. Do not confuse it with licorice.

What it is

First, the identity question: because "madhuka" is genuinely ambiguous. The Ayurvedic Pharmacopoeia of India (Part I, Volume II) lists Madhūka (flower) as Madhuca indica, synonymous with Madhuca longifolia, the mahua tree, and explicitly warns it is "not to be confused with Madhuka (Glycyrrhiza glabra)", i.e., licorice root (Khare's Ayurvedic Pharmacopoeial encyclopedia, citing API). Meanwhile, in Kerala Ayurvedic usage the drug "Madhuka" (Irattimadhuram) is identified in the API as Glycyrrhiza glabra: licorice (market-sample study citing API). One name, two drugs: this article covers mahua flower only, not licorice.

Mahua (Madhuca longifolia (Koenig) Macbride, family Sapotaceae) is a large deciduous tree of central India's forests, also called the Indian butter tree. Its cream-colored, fleshy, sugar-rich flowers fall in clusters in spring and are gathered as both food and medicine. The parts used are the flower and heartwood, with the seed yielding mahua oil (Kerala Agricultural University medicinal-plants database).

Traditional use

The flower has a long history of traditional use across Southeast Asia for fever, inflammation, rheumatism, ulcers, skin ailments, and heart complaints: and in India it is commonly consumed as a regular food item, used as a tonic, appetizer, galactagogue, and carminative, particularly among rural populations near plantations (2025 flower review). An Ayurveda college materia medica lists the flower for wasting-type debility and thirst/fever conditions, the fruit in respiratory complaints, and the seed oil for skin diseases and chronic rheumatism (Ahalia Ayurveda Medical College). The bark is described as astringent and tonic (KAU database). These are traditional and ethnobotanical uses: the clinical evidence is assessed below.

What modern research says

Human trials: none

The central finding of a comprehensive 2025 review of the flower is blunt: "Till date no clinical trials have been conducted on the therapeutic efficacy of the flower." The review's literature search (2000–2025 across PubMed, Scopus, Web of Science, and others) found only in-vitro and small animal studies. It concludes the flower's therapeutic potential "has not been scientifically validated" and calls for human studies to bridge traditional use and modern pharmacology (2025 flower review, PubMed).

Preclinical findings (laboratory and animal studies)

In-vitro work indicates strong antioxidant activity. The few in-vivo animal studies report hepatoprotective, anti-dyslipidemic, and antidepressant-type properties: but the review characterizes this animal literature as "miniscule" (2025 flower review).

Constituents identified

The flower's reported bioactives include rutin, quercetin, Mi-saponins A and B, madhucosides A and B, gallic acid, and ascorbic acid: consistent with its antioxidant reputation in the laboratory (2025 flower review). Identifying constituents is not the same as demonstrating a therapeutic effect.

Dosage

There are no clinical-trial doses for mahua flower: no human trial has tested one. No dose has been established in any human trial. Traditional teaching sources cite classical figures, but none is evidence-based, and this article gives no dosage recommendation.

Safety & contraindications

The most reassuring safety fact is also the most limited: mahua flowers have a long history of consumption as food in rural India (2025 flower review): but food use is not the same as medicinal-dose safety, and no controlled human safety studies of the flower as a medicine were identified. Treat concentrated extracts with the usual caution: avoid in pregnancy and breastfeeding for lack of data, and consult a qualified practitioner before medicinal use, especially alongside prescription medicines.

FAQs

Is madhuka the same as licorice?

Not necessarily: and that is exactly the trap. The name "madhuka" is used for two different drugs: mahua flower (Madhuca longifolia) in the API's Madhūka (flower) monograph, and licorice root (Glycyrrhiza glabra) in Kerala Ayurvedic usage. Always check the botanical name on the label (API citations via Khare; JETIR).

What is mahua flower traditionally used for?

Fever, inflammation, rheumatism, ulcers, skin ailments, and heart complaints in traditional practice: plus everyday use as a tonic, appetizer, and food among rural communities (2025 flower review). These are traditional uses, not proven effects.

Are there any clinical trials on mahua flower?

No. A comprehensive 2025 review found no clinical trials of the flower's therapeutic efficacy; all pharmacological evidence is preclinical (2025 flower review, PubMed).

Is mahua flower safe?

It has a long history as a food, which is reassuring but not proof of medicinal-dose safety: no controlled human safety studies were identified. Use medicinal preparations only with qualified guidance (2025 flower review).

What is the dose of madhuka?

There is no evidence-based dose: no human trial has tested any dose of mahua flower.
