CHEEKY HERBS monthly newsletter from tinderbox YULE - JUNE 2015 ISSUE No. 79 Letting the blood flow SPECIAL FEATURE R U BE FACI E N T S Rubefacient: what’s that? IN HERBALISM and aromatherapy, there is a whole group of herbs and oils that are employed specifically for their ability to dilate the capillaries, which allows for increased blood flow to the area of the body where it is applied. These are called rubefacients. A rubefacient is a substance or agent that increases the reddish coloration of the skin. The actual word 'rubefacient' derives from two Latin words: ruber meaning ‘red’, and facere that means ‘to make’ and indeed it does result in a warming sensation that causes the skin to redden. In medical terms, the rubefacient action is a regulatory response that increases blood flow to different tissues in the body through vasodilatation and is called hyperaemia (or hyperemia). Clinically, a rubefacient would be described as a counter-irritant that produces hyperaemia in tissues and manifests as ‘erythema’, because of the engorgement of vessels with oxygen- ated blood. It is advisable, however, to use an oil Irritation is base for dilution, particularly for the warmth as they accelerate metabolism the very strong wintergreen and the desired action bath because water and essential oils in the area.

For serious athletes and those in training, this natural process often doesn’t have a chance to occur and massage, light stretching and hot baths to promote blood circulation and aid the release of lactic acid from the muscles after an intense workout is often indicated. This is where the rubefacient oils come into their own, as they really catalyse removal of waste material with increased blood flow to stressed areas of the body. Athlete’s aromatic friends Essential oils are powerful anti-inflammatory healers and regenera- tors of skin, muscle and connective tissue as well as relieving stress and accordingly offer amazing healing support for athletes who too often sustain injuries such as sprains, strains and bruises common in many sports. Pre- and post- exercise (or competition) massage with select plant oils and extracts plays an important part in warming up the muscles before exertion and removing lactic acid (thereby speeding recovery) after a high physical output.
