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 opposite, leathery leaves are elliptic, oblong, or lanceolate in shape; they are dark green on top and have silvery scales beneath. The fragrant white flowers grow in axillary panicles that are shorter than the leaves. The fruit is an oblong or nearly round drupe which is shiny black when ripe.

Legends, Myths and Stories

Pure virgin olive oil helps reduce serum cholesterol. A monosaturated acid-rich diet that includes olive oil may be the reason for the low cholesterol plasma levels found in Italy and Greece. Best of all, lowering cholesterol levels with natural products that have no side-effects is, by some people’s opinion, better than taking cholesterol-lowering drugs that may trigger other conditions such as psoriasis or worsen it, or have far worse side-effects, some of which are still unknown. Scientific studies in France, Yugoslavia and elsewhere have shown that daily doses of olive oil can effectively reduce blood cholesterol.

In the prehistoric Neolithic period, men in the Near East and the eastern Mediterranean area were already cultivating the olive tree, mainly for its oil. Since then, olive oil has served primarily as a food, but also as a fuel for lamps, as medicine, as an emollient for dry skin, and as an anointing oil for religious purposes. In many countries, from the Orient to the Mediterranean, the olive has been a symbol of peace and wealth. It is also regarded as a sign of safe travel, from the biblical accounts of the dove’s bringing back an olive leaf to Noah on Mount Ararat to indicate that the waters of the flood had nearly subsided.

According to Greek myth, the goddess of wisdom, Athene, taught men the use of the olive tree. Both Athene and Poseidon, the god of the sea, wanted to be the patron of Attica, the section of Greece that includes the city of Athens. The other gods on Mount Olympus devised a contest for them, specifying that the winner would be the one who could provide the best gift to the people of Attica. Poseidon struck the ground with his trident, and a horse sprang forth; Athene did likewise with her spear, and an olive tree grew up. The gods decided that the olive, as a symbol of peace and agriculture, was a much better gift than Poseidon’s horse, a symbol of war. So Athene became the patron of Attica, and its principal city was named after her. Hardly by coincidence, Attica was the number one producer of olives in all of Greece.

Olive trees are known to live a long time, some well over a thousand years. It is claimed that some olive trees growing in the garden of Gethsemane date back to the time of Christ. Olive oil is similar to sesame seed oil.

Since biblical times, the olive branch has been a symbol of peace and prosperity.

A decoction of Olive leaves or inner bark of the tree is effective against fever, mild tranquilizer, and treats stomach ulcers. An infusion of the leaves has a tranquilizing effect helpful for nervous tension and lower blood pressure by dilating blood vessels. Olive oil taken internally increases secretion of bile and acts as a laxative by encouraging muscular contraction in the bowels and is reported to be a good preventative of gallstones or to help in the eviction of the gallstones. Relieves constipation. It is also soothing to mucous membrane and is said to dissolve blood cholesterol. Olive oil is high in monounsaturated fats, and has the ability to reduce the “bad” cholesterol (LDL) in the blood without reducing the good cholesterol (HDL). Studies show that a diet high in olive oil will result in a lower incidence of heart disease, rather than those who eat diets high in other forms of fat. (To prevent heart disease, nutritionists recommend limiting daily intake of fat calories to 30% of total daily caloric intake, and 10% to 15% of that should be monounsaturates such as olive oil. Olive oil is useful externally for burns, bruises, insect bites, sprains, bursitis, dry scalp, dry hair, and intense itching (pruritus). With alcohol it makes a good hair tonic, and with oil of rosemary a good treatment for dandruff. One of its most common uses is as a base for liniments and ointments. Olive oil enters into the manufacture of cosmetics, toilet soaps, hair preparations, shampoos, and skin lotions.
