After years of having varicose veins in my right thigh, I finally asked my MD for something for the pain. Instead of a pain medication he suggested I try Horse Chestnut Seed Extract. I researched in on the internet. The chinese have been using it for 500 years. You have to convert the measurements of the extract to your needs. I take the capsule form. The HCSE can be purchased at health food stores. Within a week I could actually rub my thigh without pain. I have not had any side affects either!
