Can patients with ADHD take Rehmannia glutinosa (Sh熟地黄)?

Patients with ADHD can consume a moderate amount of cooked rehmannia (Shu Di Huang), but its suitability should be determined according to individual body constitution and specific medical condition. If uncertain, it is recommended to consult a healthcare professional in advance. Detailed explanations are as follows:

Cooked rehmannia has functions of nourishing yin and blood, and enriching essence and marrow. It may help improve symptoms such as fatigue and inattention caused by liver and kidney deficiency or qi and blood insufficiency. For ADHD patients who also show signs of physical weakness, moderate consumption of cooked rehmannia might help regulate overall health. However, cooked rehmannia is rich and greasy in nature and excessive intake may burden the spleen and stomach, impair digestive function, and even cause discomfort such as abdominal distension or reduced appetite. Therefore, the dosage must be carefully controlled.

If a patient presents symptoms of internal damp-heat or has weak spleen and stomach function, cooked rehmannia is not recommended. Its rich and greasy nature may exacerbate internal accumulation of damp-heat, manifesting as symptoms like dryness and bitterness in the mouth, thick greasy tongue coating, or sticky bowel movements. Moreover, ADHD has complex etiologies, and relying solely on cooked rehmannia cannot address the core issues.

Some individuals may be allergic to cooked rehmannia and develop allergic reactions such as rashes or itching. In such cases, usage should be discontinued immediately and medical advice should be sought.
