Also known by its brand name “Granulex”, this medication which combines balsam Peru, castor oil, and trypsin topical, is used to “treat bed sores and other skin ulcers”. Plus, it can also help accelerate healing and relieve pain caused by said conditions. The reason balsam Peru, castor oil, and trypsin topical are combined together in this treatment is because Balsam Peru, for instance, “increases blood flow to a wound area, and also helps fight bacteria”, while Castor oil “prevents skin cells from breaking down, which aids in wound healing”. And as for Trypsin, it helps remove damaged skin cells. Before using this ointment, remember to tell your doctor about your allergies, or if you’re using other drugs that might interact with “Balsam Peru-castor oil-Trypsin” combination medicine. You should also tell them if you are pregnant or if you plan on becoming pregnant before using this treatment, because after all, you need to get your doctor’s professional advice. According to drugs.com, “treating a skin wound may increase your risk of developing an infection”. Therefore, you should call your doctor when you have fever, chills, rapid heart rate, flu symptoms, or mouth and throat ulcers, considering these are indicative of infection. As for the common side effects, they’re fortunately less serious such as “mild stinging or burning where the medicine is applied”.
