Dosage Of Barberry
A Barberry formulation, such as the one mentioned below, can be taken at the rate of 1 capsules, or 15 drops, 3 times a day. A 3 month course is often about right.

An ointment made from a 10% extract of Barberry can be applied to the skin three times per day.

A tea/infusion can be prepared using 2 grams of the herb in a cup of boiling water. This can be repeated two to three times daily.

For a decoction, put l teaspoonful of the bark into a cup of cold water and bring to the boil. Leave for l0-l5 minutes. This should be taken three times a day.

Combinations
In gall-bladder diseases Barberry combines well with Fringe Tree Bark and Black Root. A combination can also be made with Barberry, Wild Yam, Dandelion, Cramp Bark, Peppermint, Catnep, Fennel and Ginger. This valuable formulation will generally support the liver if continued for 3 months or so. It is also available as part of a 90-day Liver Programme, which includes two additional products and a useful pamphlet. 

Cautions
Avoid Barberry if pregnant or nursing.
