Another proven winner, the Siberian Ginseng (Eleutherococcus senticosus)

This ancient Chinese tonic, rediscovered by the Russians after World War II, helps people to withstand stress. It appears to benefit the whole body, sharpening physical and mental performance and restoring vitality during times of overwork or illness.

What It Is
Also called eleuthero, Siberian ginseng is a distant botanical cousin of Panax ginseng, which is better known. Although not as revered (or expensive) as the Panax species, Siberian ginseng has been used in China for thousands of years to enhance the body's vital energy (qi), restore memory, and prevent colds and flu. It is derived from Eleutherococcus senticosus, a plant native to eastern Russia, China, Korea and Japan. Supplements are usually made from the dried roots.

The herb gained prominence among Western doctors in the 1950s, after a Russian health researcher, I. I. Brekhman, completed experiments examining its effects on thousands of men and women. His studies demonstrated that Siberian ginseng could help healthy people to withstand physical stress, improve their immune systems, and increase their mental and physical performance. Subsequent research revealed the herbs potential for treating specific ailments.

It heightens mental alertness and allows the mind to focus in adverse situations. By reducing the effects of stress and supporting the immune system. Siberian ginseng may also be of value in decreasing the risk of many chronic illnesses.

Major Benefits
Siberian ginseng is often recommended as a general revitalizer for people who are fatigued (including those recovering from illness and those who are overworked). It’s also recommended for people whose ability to work is impaired, or for those with poor concentration. Studies in Russia involving 2100 healthy men and women aged 19 to 72 who were given extracts of the herb found that ginseng improved the following: physical labor performance; proofreading accuracy; radio telegraphists’ speed and precision in noisy surroundings; people's ability to adapt to high temperatures, as well as to a high-altitude, low-oxygen environment; and their ability to withstand motion sickness.

Because it also enhances immunity, Siberian ginseng is frequently included in nutritional support programs for people with chronic fatigue syndrome or fibromyalgia. In addition, it may benefit people in the early stages of Alzheimer's disease by increasing mental alertness.

Additional Benefits

Taken between menstrual periods, it may also be useful in preventing female infertility. The herb may be suitable as a fertility aid for men as well. When alternated with Panax ginseng, it may be of value for some cases of impotence.

Traditionally, the Chinese have used Siberian ginseng to suppress colds and flu. The herbs efficacy may partly be related to its ability to boost the immune system. Russian studies support this use. In a very large study, more than 13000 car factory employees who took the herb one winter reported suffering 40% fewer respiratory tract infections during that period than in previous winters. It has also been used to treat certain heart conditions and to lower blood sugar. Test-tube studies suggest that Siberian ginseng may help to protect against some types of cancer or to boost the effects of conventional chemotherapy drugs. More studies are needed to verify these and other potential benefits.

How To Take It

• Dosage: For stress, fatigue and other complaints: Take 100-300 mg of a standardized extract of Siberian ginseng two or three times a day. For menstrual disorders: Mix Siberian ginseng with herbs such as chaste tree, dong quai and licorice. Commercial combinations are available.
• Guidelines for use: Siberian ginseng can be taken long term. However, some authorities suggest using it for three months and then stopping for a week or two. German health authorities do not recommend it for people with high blood pressure, though there are few studies to indicate any adverse reactions in this group.
