Can Lily Bulb and Prepared Rehmannia Root be taken together?
Generally speaking, lily and prepared rehmannia can be consumed together, but they should be used in appropriate amounts under the guidance of a professional traditional Chinese medicine practitioner. The detailed explanation is as follows:

Lily has various effects, including nourishing yin and moistening the lungs, clearing the heart and calming the mind, and relieving cough by moistening the lungs. Prepared rehmannia root is used to nourish the blood and yin, enrich essence and marrow, and reduce fire caused by yin deficiency. It can be used to treat conditions such as blood deficiency with sallow complexion, palpitations, and irregular menstruation. According to traditional Chinese medicine theory, there are no obvious contraindications between lily and prepared rehmannia, so they can be used together. When combined, their effects complement each other and can be used for nourishing kidney yin, clearing heat and moistening the lungs, and calming the heart and mind.
However, both lily and prepared rehmannia are relatively rich and greasy in nature. People with spleen and stomach deficiency cold or indigestion may experience increased burden on the spleen and stomach when consumed in excessive amounts, leading to discomforts such as abdominal distension and diarrhea. Those with excessive internal damp-heat may experience increased dampness and heat after consumption, worsening symptoms of damp-heat in the body. Therefore, it is recommended to consult a TCM practitioner or nutritionist before consuming lily and prepared rehmannia, and appropriately combine ingredients according to individual constitution and health condition.
In daily life, it is recommended to maintain good living habits during the period of use, avoid excessive fatigue and mental stress, to promote physical recovery.
