Origin & History
Gallnut is an excrescence formed on the twigs of oak trees, primarily Quercus infectoria and related species, native to China, Turkey, Iran, and Southeast Asia. It is highly valued in functional nutrition for its exceptional richness in tannins, offering potent astringent, antimicrobial, and anti-inflammatory properties.
“With a history spanning over 2,000 years, Gallnut has been a cornerstone in Traditional Chinese Medicine, Persian medicine, and Ayurveda. Valued for its 'astringent cooling' nature, it was traditionally applied to wounds, ulcers, and gastrointestinal issues, and is referenced in classical texts such as the Compendium of Materia Medica and Unani pharmacopoeia.”Traditional Medicine

Frequently Asked Questions
What is Gallnut?
Gallnut is not technically a nut but a gall — an abnormal growth formed on oak trees (primarily Quercus infectoria) in response to wasp larvae. It is exceptionally rich in tannins (50-70% by weight), particularly gallotannins and gallic acid, and has been used for centuries in traditional medicine systems across Asia and the Middle East.
What is the recommended dosage and is Gallnut safe?
For internal use, 250-500 mg of powdered gallnut daily is commonly suggested. Due to its very high tannin content, prolonged or excessive internal use can cause digestive issues and may impair nutrient absorption. It should be separated from medications and iron supplements by at least 2 hours.
What are the proven benefits of Gallnut?
Research supports Gallnut's antimicrobial activity against various bacteria and fungi, its anti-inflammatory effects, and its efficacy in oral health applications such as reducing gum inflammation. Most evidence comes from in vitro and animal studies, with limited but supportive human clinical data for topical and oral health uses.
