HS II is an herbal combination designed for the circulatory system, and more particularly, the heart. It is based on three herbs: hawthorn berries, capsicum and garlic.
Hawthorn berry is a “bitter” that is famous in Europe as a heart stimulant. It assists the body in strengthening all the heart tissues and is considered by herbalists to be a specific heart tonic. Hawthorn’s nutritional effects are felt very slowly, and much of its overall benefit seems to be related to certain flavonoids it contains. These help the body open up constricted blood vessels, having a general dilating effect. This in turn leads to increased blood flow to the heart.
Capsicum is an aromatic herb that promotes blood flow to the extremities. It contains valuable nutrients like vitamins A, B, and C with iron and calcium. It is a nervine herb, which is beneficial for a healthy heart rhythm.
Garlic is one of the oldest of all herbs used by man. It is an aromatic herb and is reported to have beneficial effects for both the circulatory and immune systems. It helps the body to normalize blood pressure while improving blood circulation at the same time.

The unripe hulls of the black walnut contain vitamin C.
It also has oxygenating abilities which help burn up excess toxins and fatty materials. It aids in regulating blood sugar levels, and has been used for herpes, impetigo, athlete’s foot and ringworm.
