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!

Description of Plant(s) and Culture

Yerba santa is an evergreen shrub; it is somewhat branching and grows to a height of 2-4 feet. The stems are smooth and exude a gummy substance. Leaves are 3-4 inches long, distinctively woolly on the undersides, containing a network of prominent veins, and the resinous substance appears as if the woolly fibers have been varnished; upper surface is smooth with depressed veins. The flowers are terminal, appearing in shades of dark lavender to pale shades of lavender to white; forming funnel-shaped clusters at the top of the plant. The honey is amber, with a slightly spicy flavor. Bees love this plant. The capsule fruit is oval, grayish-brown and contains small brown shriveled seeds.

Legends, Myths and Stories

The name yerba santa (means “Holy weed”) was given by the Spanish fathers who became aware of it through Native Americans.

The Native Americans smoked or chewed the leaves for asthma. The taste is peculiar, at first, when chewed, seems rather disagreeable, resinous, and bitter. This taste soon disappears and then tastes sweet and cooling, which is especially noticed when chewing stops a minute, or by drinking a glass of water. One Native American expressed it, “It makes one taste kind of sweety inside.”

Native Americans boiled the fresh or dried leaves for colds, coughs, sore throat, catarrh, asthma, bronchitis, hayfever, congestion due to allergies, laryngitis, fever, stomach aches, vomiting, diarrhea, hemorrhoids, kidney conditions, and rheumatism. Externally, Native Americans used the fresh or dried leaves as a poultice for broken or unbroken skin, fatigued limbs, insect bites, sprains, bruises, swellings, sores, poison ivy or poison oak rashes.
