Overview

Arabinogalactan is a starch-like chemical that is found in many plants. It is found in highest concentrations in larch trees. Most of the larch arabinogalactan found in stores is produced from western larch or eastern larch trees. But larch arabinogalactan can also be produced by other larch tree species. Larch arabinogalactan is sometimes used for medicine.

Larch arabinogalactan is used for common cold, flu (influenza), ear infection (otitis media), and many other conditions, but there is no good scientific evidence to support its use.

In foods, larch arabinogalactan is used as a stabilizer, binder, and sweetener.
