Tongue: Red with little liquid, or else green-blue. Pulse: Rough and rapid.
Method: Decoct with water.
Rationale: Raw and Shú dì huáng and Dāng guī nourish the blood and moisten dryness. Táo rén and Hóng huā quicken the blood and dispel phlegm. Shēng má upbears the clear while Bīng láng downbears the turbid. Bīng láng combined with Táo rén expels stasis and breaks binds, as well as loosening the chest and diaphragm. Moreover, the Bīng láng also ensures that the raw and Shú dì huáng enrich yīn and nourish the blood without clogging the stomach. Zhì gān cǎo helps the Bīng láng to rectify qì and harmonize the stomach.
