Rehmannia (raw) shēng dì huáng · 生地黄

Rehmannia glutinosa (raw root)

Nature and flavour. Sweet and bitter, cold; Heart, Liver and Kidney systems.

The raw root is classically described as cooling the blood and nourishing yin - a different herb in use from the prepared root, which tonifies blood.

性味归经。甘、苦,寒;归心、肝、肾经。

生地黄传统上用于清热凉血、养阴,与炮制后的熟地黄(补血药)功用不同,实为两味。

Classical category · no formulas, no dosages, no herb-drug combinations are given.
Safety. Cold in nature and classically avoided where digestion is weak or there is diarrhoea. The blood-tonifying form is the prepared root (shu di huang), not this one.

性寒,传统上脾胃虚弱或腹泻者不宜。补血用的是炮制后的熟地黄,不是这一味。
