10 to 15 grams in decoction. The maximum dosage of Shan Zha is 30 grams. The unprocessed herb dissolves food stagnation and activates blood circulation. Dry-fry- ing the herb reduces the sour taste and astringent property of the herb, thereby harmonizing the overall effect. Blackening the herb increases the bitter taste, which potentiates its effect to reduce abdominal distention and relieve diarrhea. Charring, that is, burning the herb to ash, enhances its influence to stop bleeding.
CAUTIONS I CONTRAINDICA TIONS
