Isabgol is blond psyllium, a small winter herb whose seed husk swells into a smooth gel in water. India grows most of the world’s psyllium, chiefly in north Gujarat and western Rajasthan, and Unjha in Mehsana is the main trading town. The husk is sold as a bulk fibre for constipation and stirred into water, milk or curd. The name isabgol comes from Persian words for horse’s ear, describing the seed’s shape.

How to recognise Isabgol
It is a low annual, usually ankle- to shin-high, with a tuft of narrow, grass-like, softly hairy leaves.
Thin stalks rise from the tuft, each ending in a short, dense, cylindrical spike of tiny whitish flowers.
Each capsule holds two boat-shaped seeds that are pinkish-grey and coated with a thin, translucent husk.
When wet, the husk swells many times over into a clear, slippery gel.
Wheat bran is a flaky, brown cereal husk that does not form a gel.
Traditional use of Isabgol
Household
A spoon of husk in water or warm milk at night is a common Indian home remedy for constipation, and in curd for loose stools.
Indian household practice
Kitchen
In gluten-free baking, a little psyllium husk binds dough in place of gluten.
Modern baking practice
Farming
It is sown in November and harvested in February or March; rain near harvest makes the seed swell and shatter, so dry winters suit it.
Gujarat and Rajasthan farm practice
Modern notes on Isabgol
Psyllium is a soluble fibre that adds bulk and water to stool, and clinical trials support it for both constipation and mild diarrhoea.
In 1998 the United States FDA allowed foods with psyllium to claim a reduced risk of heart disease, based on trials showing modest cholesterol lowering.
It can slow sugar absorption after meals and is studied as an aid in type 2 diabetes alongside treatment.
Nurses and factory workers who often handle the powder can develop allergic asthma from breathing it.
Isabgol safety
Always take it with a full glass of water and do not use it if you have trouble swallowing or a narrowed gut. Take other medicines two hours apart, since the gel can reduce their absorption.
Ecology and sourcing
It is native to dry regions from the Canary Islands and North Africa through the Middle East to India.
It needs cool, dry winters and sandy loam, which is why north Gujarat suits it.
Its short crop cycle fits between other crops on irrigated farms.
