Peripheral vasodilators work by relaxing the smooth muscles in blood vessel walls, allowing for increased blood flow to the extremities. These substances are particularly helpful for conditions like Raynaud’s syndrome, poor circulation, and cold hands and feet. Herbal examples include ginkgo (Ginkgo biloba), which enhances microcirculation and oxygen delivery, cayenne pepper (Capsicum annuum), which stimulates blood flow and promotes warmth, and ginger (Zingiber officinale), known for its circulatory and warming effects. Peripheral vasodilators may also assist in managing blood pressure and reducing vascular strain in the outer areas of the body.
