anytime I try horse chestnut I have stomach problems,
what can be a reason for that? I'd like to improve circulation in my legs so horse chestnut is right choice,
what does it have that irritate my guts?
Horse chestnut is listed as being a bit toxic, though most people can handle it. It is used as a topical application in creams and lotions designed to help varicose veins and in some body wraps. Butchers broom might also work for you for improving circulation.
