    Many people are not aware the most healing herbs make up today’s modern medicine. The healing herbs from ancient days are still the healing herbs of modern times. Throughout all of these years herbs have remained unchanged; their quality remain as strong as ancient man and animals found it to be thousands of years ago. What has changed is the way man uses these healing herbs together with modern medicine of today.

Ancient man knew about the many benefits of healing herbs and passed on their knowledge form generation to generation. Today modern man continues to benefit from the wisdom ages ago. Actually, herbs can be any plant, flower, tree or shrub(灌木) that heals the body. According to early writings, man first noticed that when an animal was ill it would bite into specific plants, otherwise the animal will leave them alone.

Observing animal behaviors is still done today. Ten years ago, researchers at the Gombe Stream National Park in Tanzania, noticed chimpanzees(黑猩猩) that were ill were eating Aspirin leaves. Researchers found that Aspirin leaves contained a kind of antibiotic(抗生素). These chimpanzees no doubt knew this plant would help heal their disease.

Most plant life has a pleasant smell. The writings of ancient man note that people rubbed these sweet plants on their bodies to keep insects away.

Some herbs mask the smell of smelly meat. The Egyptians used a variety of herbs to preserve their dead.

In conclusion, ancient herbs had a variety of purposes, and for thousands of years were used for the preservation of our foods, and to heal our bodies. Herbs can continue to play an important part in our lives if we open our minds to their importance and usefulness. In my opinion, it is always better to treat naturally with herbs, than to treat illnesses with man-made medicines. There are few if any side effects to taking herbs.
