1. Herbal supplements are growing in popularity as people
seek out safe, natural alternatives to pharmaceutical
drugs. Modern research is discovering the active
ingredients in many herbs that have been used
medicinally for hundreds of years. The herbs described
below are widely available and recommended for
particular health conditions.

2. Ginko biloba is a tree that grows in mountainous regions
of China. Compounds in its leaves work to lower high
blood pressure by widening the arteries. Improved
circulation to the brain enhances concentration, alertness
and memory. The herb is also a source of antioxidants
which protect cells from damage and help to defend
against cancer.

3. Gotu kola is red-flowered herb that grows in swampy
areas. Molecules in the leaves called triterpenes help to
reduce swelling and improve circulation. Gotu kola is most
commonly taken as a treatment for varicose veins. It
improves vascular tone and elasticity, reducing the leakage
that causes blood vessels to bulge.

4. Hoodia Gordonii is a succulent resembling a cactus. Found
in the Kalahari desert, it was traditionally used by San
Bushmen to keep hunger and thirst at bay during lengthy
hunting trips. In the West, Hoodia has been hailed as an
amazing aid to weight loss. A steroidal glycoside in the
plant called P57 suppresses the appetite, allowing people
to diet without feeling hungry.

5. Milk thistle is a plant related to the sunflower. It's seeds
contain a compound called silymarin, which is effective for
detoxifying the liver. Milk thistle helps to protect the liver
from the damaging effects of chemicals and medications,
including those used in chemotherapy. It also promotes
the regeneration and repair of liver cells.

6. Saw palmetto is a small palm found in southeastern
America. Native Americans used its berries as a remedy
for male urinary and reproductive problems. Today, the
herb is frequently recommended for men diagnosed with
benign prostatic hyperplasia (non-cancerous prostate
enlargement). It helps to improve the urinary difficulties
associated with BPH.

7. Valerian is a flowering plant which grows in Europe and
Asia. Its root was valued by the ancient Greeks and
Romans for its sedative properties. Valerian is still taken
by people who suffer from insomnia. Many prefer it to
prescription tranquilizers which could become addictive.

8. Consult a doctor if you intend to begin taking herbal
supplements. Although they are produced from natural
sources, they contain medically active ingredients. Certain
herbs should not be taken along with common
prescription medications. Others are unsuitable for
pregnant women or people with chronic conditions.
