Is it safe to take Rehmannia glutinosa combined with Cornus officinalis?

Generally speaking, it is acceptable to consume Rehmannia root combined with Cornus officinalis, but it should be taken in appropriate amounts under the guidance of a physician. The specific analysis is as follows:

When consumed together in appropriate amounts, their therapeutic effects can complement each other, enhancing the effect of nourishing yin and benefiting the kidneys, and treating conditions such as dizziness and tinnitus (What causes dizziness and tinnitus), weakness and soreness of the waist and knees, and impotence.

However, for individuals with a constitution prone to yang deficiency and cold-dampness, or those experiencing symptoms such as spleen-stomach cold deficiency, indigestion, or diarrhea, the combination of Rehmannia root and Cornus officinalis may be excessively nourishing and greasy, making it difficult to digest and absorb, and could even exacerbate internal cold-dampness, leading to problems such as abdominal distension and reduced appetite. Therefore, prior to deciding to consume Rehmannia root combined with Cornus officinalis, one should consult a qualified traditional Chinese medicine practitioner to ensure appropriate treatment based on individual conditions.
