Can a 20-year-old take Rehmannia glutinosa (Shu Di Huang)?

Twenty-year-olds can usually take prepared rehmannia, but it is important to use the medication under a doctor's guidance. If any physical discomfort occurs, it is recommended to seek medical attention promptly and follow the doctor's instructions for treatment.

As a traditional Chinese medicine, prepared rehmannia has the functions of nourishing yin and benefiting the kidneys, as well as nourishing the blood and calming the mind. If individuals aged 20 exhibit symptoms of kidney yin deficiency, such as soreness and weakness in the lower back and knees, dizziness, tinnitus, dry mouth and throat, insomnia, and excessive dreaming, moderate use of prepared rehmannia can help nourish kidney yin. For those showing symptoms of blood deficiency, such as pale complexion, palpitations and insomnia, or irregular menstruation, prepared rehmannia can aid in nourishing the blood and calming the mind.

It should be noted that prepared rehmannia has a rich and greasy nature, making it difficult to digest, so caution should be exercised when using it, and it should be taken in accordance with a doctor's advice. Particularly for individuals without related symptoms or whose body constitution is unsuitable, taking prepared rehmannia casually should be avoided to prevent adverse effects on the body.

During the period of taking prepared rehmannia, attention should also be paid to adjusting dietary habits, maintaining a light diet, and avoiding spicy, stimulating, or greasy foods, which may affect the efficacy of the medication.
