Compound glycyrrhizin tablets have anti-inflammatory, anti-allergic, immune modulating and hepatoprotective effects, and are widely used in dermatology, such as eczema, acute urticaria and psoriasis, etc. Compound glycyrrhizin can be chosen for treatment. There is also a difference between acute and chronic diseases as to exactly how long you should take it. Like acute urticaria, it can be stopped once the rash subsides and may take 3-5 days. For eczema, you need to consolidate the rash for 1-2 weeks after it subsides, which may be 2-3 weeks. Like psoriasis chronic skin disease, some patients may need to take it for 2-3 months, or even longer. If you take it for a long time, be careful to monitor electrolytes and blood pressure.
