Capsicum, also known as red pepper or chili pepper, has a long history of use in traditional medicine, particularly in cultures such as those in South America, Africa, and India. Capsicum was traditionally used to relieve pain, increase circulation, and improve digestion. Capsaicin, the active compound in capsicum, has been found to have anti-inflammatory and analgesic properties, making it useful in the treatment of conditions such as osteoarthritis, neuropathic pain, and headaches.
Capsicum has also been used in traditional medicine for the treatment of digestive problems such as indigestion, flatulence, and stomach ulcers. It has been found to increase secretions of digestive enzymes, which can help improve the overall digestive process.
In modern times, capsicum is used in many over-the-counter topical creams and gels for pain relief. It is also used in the manufacture of capsaicin patches for use in the treatment of conditions such as post-herpetic neuralgia, a condition that occurs after a person has had shingles.
