It is often used clinically in combination with dandelion, Yin Chen, motherwort and other traditional Chinese medicines. The adverse effects of this drug are not clear, and it is contraindicated in patients with deficiency and slippery essence. If patients have any discomfort, it is recommended to consult a doctor in time, and if you need to use the medicine, you must be guided by a professional Chinese medicine doctor. Psyllium should not be used on its own, so as not to affect the recovery of the condition.
