Burdock Root Extract Powder

The long taproot of Arctium lappa, the great burdock eaten as gobo in Japan, is the only plant part behind this extract. The root is extracted in water, concentrated and dried to a light brown powder. Seeds, leaves and the clinging burrs are not used.

This burdock root extract is a 10:1 ratio extract with no marker assay. The powder is milled to 80 mesh and disperses in water. A burdock seed extract and a burdock root powder are listed as separate products.

Arctium lappa Root Source & Identity

The botanical entity is Arctium lappa L., a biennial of the daisy family, Asteraceae, with large leaves and spiny burrs, native to Europe and Asia. The part used is the root, a thick, brown-skinned taproot that is also a vegetable. The seeds, called niubangzi in Chinese herbal practice, the leaves and the burrs are not part of this burdock root extract.

Root and seed of the same plant are different raw materials with different chemistry. Lesser burdock, Arctium minus, and woolly burdock, Arctium tomentosum, are related species. The burdock burr is also confused with the spiny fruit of Xanthium, cocklebur, which is unrelated.

The root stores inulin-type fructan carbohydrate, caffeoylquinic acids and polyacetylenes, while the lignans arctiin and arctigenin belong to the seed.

Burdock Root vs Seed Extract

Form	What It Is	Choose It When
10:1 Burdock Root Extract	Water extract of the burdock taproot, ratio-defined	A root-based extract is the brief
Burdock Seed Extract Powder	Water extract of the burdock seed, a different part	The brief is seed-based
Burdock Root Powder	Dried, milled burdock root, no extraction	Whole-root material with fibre is wanted
Burdock Seed Extract 10–40% Arctiin	Standardized seed extract with a defined arctiin level	An arctiin figure is needed in the specification

The 10:1 ratio measures root going into the burdock root extract. It is not an inulin or phenolic assay. The seed extract in the table comes from another plant part and carries lignans that the root does not, so the two extracts are not interchangeable.

The extract is the concentrated, dispersible form of the root. The root powder keeps all the fibre and behaves like a bulk vegetable ingredient.

Application Areas

Capsules for an Inulin-Rich Extract

Burdock root extract fills hard capsules after a flow check at 80 mesh. Inulin-type carbohydrates make the dried powder take up moisture, so fill in a controlled-humidity room and keep the hopper covered. If the hopper starts to arch, a glidant is the simplest fix.

Tablets with Moisture Barrier

Carbohydrate-rich root extracts soften as they pick up water. Use a dry binder, a late-added lubricant and a film coat that acts as a moisture barrier, then compare tablet hardness at pressing and after a week of storage in the final pack.

Gobo-Style Tea Sticks

Burdock root is an established tea ingredient in Japan and Korea, so tea-style sticks suit the extract. It disperses in hot water to a tan, mildly sweet and earthy cup. Roasted-grain, ginger or mild citrus flavours work well, and a taste test at the planned dose sets the fill weight.

Sachets in Sugar Carriers

Sachets carry burdock root extract in a sugar or fibre carrier. Sieve the powder into the carrier before filling, because carbohydrate-rich powders form soft lumps when poured. For burdock root, check dose uniformity at the start, middle and end of the filling run.

Bars and Premixes

the burdock root powder goes into the dry fraction of a bar recipe ahead of the binder. The earthy, mild taste suits oat, nut and seed bars, and the extract’s moisture pickup means a bar should be tested for stickiness after a week.

Formulation Notes

Burdock root extract is a light brown powder with an earthy, slightly sweet smell. In water it forms a tan, lightly hazy dispersion, and the inulin-type carbohydrate adds a little body without making the liquid syrupy. Cut or ground burdock root browns quickly in air because of its phenolic content, and the extract can darken slowly in the same way.

Stir during addition and keep portions small so the burdock root powder wets evenly. Prepare the dry blend in stages, starting with a sieved premix of the burdock root powder and a carrier portion. For burdock root, once opened, keep the container tightly closed and store it cool and dry, off the floor.
