Which of the following is NOT one of the eight methods in herbal prescription strategies?

• A. Warming
• B. Draining
• C. Astringing
• D. Dispersing

Answer: (C)

The eight methods describe broad actions used to shape an herbal formula’s overall effect on a pattern. Warming, draining, and dispersing are all classic actions you’ll see as core prescription strategies: warming reinforces interior yang to treat cold/deficiency, draining clears excess heat or fluids, and dispersing moves stagnation or exterior pathogenic factors. Astringing, by contrast, is not one of these overarching methods. It’s a specific binding effect produced by certain herbs to stabilize tissues or stop leakage, not a primary strategic action used to modify a pattern in the same way as the eight methods. So astringing isn’t counted among the eight methods, while the other options fit as recognized strategies.
