The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

Gum plant tends to take up selenium compounds (a sulphur-like non-metallic element) from the soil and store them. It becomes toxic in areas where the soil is rich in selenium; do not pick it from such areas. Large doses can be poisonous; smaller doses may cause slowing of the heartbeat. Avoid in cases of low blood pressure.

Because of its high resin content, it is considered hard on the kidneys and for this reason usually is used only for acute ailments.
