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!

The greatest value of Peruvian bark is in its quinine content, which makes it effective against malarial infection. Small doses are also good for fever (drink the tea freely for fevers), neuralgia, epilepsy, pneumonia, typhoid, diarrhea, dysentery, blood purifier, rheumatic pains, and for indigestion. Makes a good mouthwash and gargle for mouth and throat problems. It stimulates uterine contractions; should not be used during pregnancy; unless uterine contractions are desired to aid in a tardy delivery.
