What is the typical dried dosage (and fresh equivalent) for Da Ji?

• A. 9-15 g dried or 30-60 g fresh
• B. 30-60 g dried
• C. 1-2 g dried
• D. 50-100 g dried

Answer: (A)

Da Ji is a very potent purgative, so its dosing is kept modest and precise. The usual dried dose is 9–15 g, and the fresh form is used at about 30–60 g to achieve a similar effect. The difference comes from water content: fresh material has much more water, so you need more weight of the fresh plant to deliver the same concentration of active compounds found in the dried material. In practice, that’s roughly three to four times as much fresh herb as dried. This balance helps achieve the desired purgative effect while accommodating the herb’s strong potency and toxicity.
