Circulatory System

This is taken from The Ancient Art of Self-Healing by Yogi Bhajan:

The following foods increase circulation: chilies, ginseng, lecithin, lemons.

Chilies stimulate circulation

Ginseng is good for the heart and good for the circulatory system. You can have fifteen drops of ginseng extract in a glass of water four times a day, maximum.
Ginseng is also well known for its aphrodisiac qualities; it stimulates cell growth, increases hormone production, rejuvenates the nervous system, and it was referred to as a cure all for all ills (again, temper this with modern knowledge).

Lecithin has the property of affinity to oil, and when isolated from its normal surroundings (as a granular lecithin isolated from soybeans) it combines with fats free in the bloodstream and along artery walls. It is thus good for high blood pressure, heart problems and poor circulation.

Lemon juice helps to thin the blood and increase circulation.
