Rubefacient
A rubefacient is a substance that, when applied to the skin, causes reddening of the affected area. This is due to an increase in blood flow to the area, which can result in a warming sensation. Rubefacients are commonly used to treat sore muscles, rheumatic pain, and even headaches. They can also be used to treat the symptoms of colds and flu, such as congestion and sore throat. Rubefacients can be used topically, or taken internally in the form of tea, capsules, or tinctures. They work by increasing circulation to the area, which can help reduce inflammation, ease pain, and stimulate healing. Additionally, rubefacients can help to reduce the risk of infection by increasing the amount of oxygen circulating in the area.
