Generally speaking, Poria can be eaten during menstruation. Poria is a medicinal food product, which is more gentle in nature and generally does not cause abnormal menstruation. Poria is sweet and light in flavor, and flat in nature, with the effect of diuresis and seepage of dampness (promoting the operation of water to dispel dampness), strengthening the spleen, and tranquilizing the heart. It can be used for edema and low urine output, phlegm-drinking palpitations (caused by phlegm-drinking evil qi), spleen deficiency with low food intake, loose stools, diarrhea, restlessness of the heart and mind, palpitations and insomnia. Poria’s medicinal properties are more moderate, and it does not enter the blood (in the four periods of warm disease, Wei Qi and Ying Blood, it belongs to the most in-depth stage or disease), and it generally does not affect the fullness of the Chong Ren menstrual qi, so it will not change the amount of menstruation, menstrual cycle leading to abnormal periods. Attention should be paid when taking Poria, which generally needs to be decocted and used. This product is draining in nature, so it should be taken with caution for those with yin deficiency without dampness and heat, deficiency cold and slippery semen, and qi deficiency and subsidence. Chinese medicines should be used by a TCM practitioner after diagnosis and avoid self-medication.
