Radix Rehmanniae Preparata has the effects of enriching blood and nourishing yin, and can be used for treating blood deficiency, sallow, dizziness, palpitation and insomnia, irregular menstruation, metrorrhagia, etc. It can also be used for hot flashes, bone steaming, night sweats, nocturnal emission, diabetes and other symptoms caused by kidney yin deficiency. If blood deficiency or liver and kidney yin deficiency, it can be used. If not, you'd better not use it.

Comments and suggestions: In addition, this product is sticky, even worse than Radix Rehmanniae, which hinders digestion. Those who suffer from qi stagnation and excessive phlegm, abdominal distension and pain, and eat less loose stool should not take it. Long-term reuse should be equivalent to frying dried tangerine peel and kernels to prevent sticking to the stomach.
