Licorice, too, affects potassium, and the combination of licorice and loop diuretics might cause unexpectedly rapid potassium loss. 8 However, the special form of licorice known as DGL (deglycyrrhizinated licorice) should not affect potassium levels.
Loop diuretics have been reported to cause increased sensitivity to the sun, amplifying the risk of sunburn or skin rash. Because St. John's wort and dong quai may also cause this problem, taking these herbal supplements during treatment with loop diuretics might add to this risk.
It may be a good idea to wear a sunscreen or protective clothing during sun exposure if you take one of these herbs while using a loop diuretic.
