The statement “three kinds of people should not eat psyllium” is inaccurate. Generally speaking, people with kidney deficiency and spermatorrhea should be cautious of using psyllium. Psyllium is cold in nature, sweet in flavor, and belongs to the liver, kidney, lung and small intestine meridians. It has the basic efficacy of clearing away heat, diuretic and diaphoretic (improving the problem of dribbling in urine, and the problem of small volume of urine not being passed), seeping dampness and stopping diarrhea, expelling phlegm, and clarifying the eyes. This medicine is suitable for edema and distension, urinary dribbling (the feeling of not being able to urinate) and astringency, summer dampness and diarrhea, lung-heat cough, yellow and thick phlegm, eye redness and swelling pain, eye darkness and dimness, and shyness and tearfulness (the eyes are afraid of the light, and often tearful), and so on. The adverse reactions and contraindications of Psyllium Husk are not clear, and caution should be exercised in cases of kidney deficiency and seminal emission. It is advisable to decoct this product in cloth bags. Chinese medicine must be used under the guidance of a doctor, not blindly self-medication.
