Herbs may be given in different formats. Traditionally loose herbs were given for the patient to boil up to make a liquid extract (decoction) but now they can come as ground herb powders, freeze dried powders or concentrate granules which are diluted in hot water and drunk. The taste varies according to the formula and may take a little getting used to but this is usually a transient phase.
Dosage varies according to the patient's age; the condition being treated; body weight and constitution. A child will be given a proportion of the adult dose according to their body weight or age. The dosage will be advised.
