Infusion of goldenseal has the effect of clearing away heat and detoxification (removing heat and toxicity from the body), subduing swelling and relieving pain (eliminating swelling and pain), and stopping bleeding. Note that the active ingredients precipitated from boiling water infused herbs are relatively less, and their efficacy is naturally less than that of decoction. The efficacy of the decoction is not as good as that of the decoction, so it is better to take it with a variety of herbs, depending on the person and the disease. The bitter taste and slightly cold nature of goldenseal is commonly used in the treatment of upper respiratory tract infections, pharyngitis, tonsillitis, otitis media, acute conjunctivitis, acute lymphadenitis and other conditions. Note that it should be taken with caution by those who have deficiency of spleen and stomach (weak and cold spleen and stomach). Although goldenseal can be used to treat a variety of diseases, it must be used on the basis of traditional Chinese medicine diagnosis. Moreover, there are some differences in the way of administering the drug to deal with different diseases, so it is necessary to strictly follow the doctor’s instructions and use the correct usage to apply goldenseal in order to make the drug give full play to its due efficacy.
