Eight Corrections Powder

八正散 〔八正散〕bā zhèng sǎn

Source: Hé Jì Jú Fāng 和剂局方

Ingredients:

Action: Clears heat and drains fire; disinhibits water and frees strangury.

Indication: Damp-heat pouring down into the bladder, causing dribbling urination, painful urination, and reddish urine, and stone strangury or unctuous strangury.

Category: Dampness-dispelling formulas / Heat-clearing dampness-dispelling formulas

Method: The dengxincao included in the original formulas is now usually omitted.

Warnings: Contraindicated in enduring strangury patterns with severe vacuity signs. This formula should not be used for vacuity patterns that can develop from persistent damp-heat strangury.

Rationale: Mù tōng, Qú mài, Chē qián zǐ, Biǎn xù, and Huá shí clear heat and free strangury; they clear and disinhibit lower-burner damp-heat, hence they eliminate the root of the disorder and address the main signs. Zhī zǐ clears triple-burner heat and Dēng xīn cǎo helps to abduct the heat downward. Dà huáng drains heat and, combined with Mù tōng, frees the stool and disinhibits water, drains heat and downbears fire. Gān cǎo helps to relieve pain and prevents the cold bitter agents from damaging the stomach.
