Interaction Details
There were no interactions found between Metronidazole and Catechu. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Catechu Overview
Catechu, also known as catechu gum or catechu extract, is a natural substance that is extracted from the Acacia catechu tree, which is native to parts of Asia. It is a brown, sticky substance that is used in traditional medicine and as a natural dye.
Catechu has a number of potential health benefits and has been used in traditional medicine for centuries. It is believed to have astringent, anti-inflammatory, and antioxidant properties, and it is often used to treat a range of health conditions, including gastrointestinal disorders, mouth sores, and skin wounds.
Metronidazole Overview
-
Metronidazole capsules and tablets are used to treat infections of the reproductive system, gastrointestinal (GI) tract, skin, heart, bone, joint, lung, blood, nervous system, and other areas of the body. Metronidazole capsules and tablets are also used to treat sexually transmitted diseases (STDs). Metronidazole extended-release (long-acting) tablets are used to treat bacterial vaginosis (an infection caused by too much of certain types of harmful bacteria in the vagina) in women. Metronidazole is in a class of medications called nitroimidazole antimicrobials. It works by stopping the growth of bacteria.
-
Antibiotics will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
