Can patients with favism (G6PD deficiency) take Rehmannia glutinosa (Sh熟地黄)?

Fava bean disease patients can generally consume prepared rehmannia in moderation, but whether it is suitable depends on the individual's specific condition and physical constitution. If any abnormalities occur, prompt medical attention is recommended. Detailed analysis is as follows:

Fava bean disease is a hereditary metabolic disorder, and patients may experience hemolytic reactions after consuming certain foods or medications. Prepared rehmannia has functions of nourishing yin, enriching blood, and benefiting marrow, possibly helping to regulate weakness symptoms caused by deficiency of qi and blood or insufficiency of liver and kidney. Dietary and medication choices for fava bean disease patients require special attention to avoid oxidative substances. Since prepared rehmannia is not an oxidative herb, it generally does not cause problems when used in appropriate amounts.

If fava bean disease patients have symptoms of damp-heat accumulation in the body or are currently taking other medications, they should not consume prepared rehmannia. Prepared rehmannia has a rich and greasy nature that may exacerbate internal accumulation of damp-heat, causing symptoms such as thick greasy tongue coating, abdominal distension, or indigestion. Additionally, consuming prepared rehmannia blindly may interact with other medications, affecting disease management or treatment effectiveness.

Moreover, for individuals with weak spleen and stomach function, excessive consumption of prepared rehmannia may impose additional burden and even disrupt bodily balance.
