Preparation
Powder and Capsule
It is best to use commercially prepared powdered herbs. However, if preparing at home, it is best to grind herbs with a mortar and pestle. Grinding them in a domestic grinder generates heat, which can cause chemical changes in the herbs. Hard roots can also damage the grinder.
The two-part gelatin or vegetarian capsules are available from specialty suppliers, or they can be ordered through your local health food store. Size 00 holds 200-250 mg of powdered herb.
To fill capsules: Wash hands thoroughly. Pour the powdered herb into a saucer. Separate the two halves of the capsule and slide both through the powder, scooping it into the capsule. Fit the two halves together and store in a dark glass jar in a cool place.
