Aside from producing quality paper, the eucalpytus tree also has medicinal uses up its sleeves, er, branches. Below are some alternative ways to treating the common cold and other illnesses courtesy of the most widely planted hardwood species in the world.

Medicinal Uses of Eucalyptus

Drinking and gargling tea made from eucalyptus leaves can leave you with more than fresh breath. It can also sooth sore throat and is even known to treat bronchitis and sinusitis.

It is even helpful in fighting coughs and the common cold. In fact, eucalyptus can be found in cough syrups, lozenges, rubs and vapor baths throughout the United States and Europe.

Eucalpytus oil or its active ingrdient, cineole (also eucalyptol), on the other hand can be found in liquids, ointments, mouthwashes, and even toothpastes. Topically, it can be used to treat arthritis, boils, in disinfecting wounds, and as insect repellent. The oil's scent is so potent that herbalists even use it to revive someone who has fainted.

Tree Cautions

Though apparently healthful and helpful, herbs should be taken with caution, as they can cause side effects when combined with other hers, supplements, or medications.

Those for example with liver disease and low or high blood pressure should not take eucalyptus leaf extract. Leaf preparations when taken in large amounts, can cause kidney and liver damage. People with asthma must use eucalpytus with care as it may trigger an attack.

Children are also not advised to ingest eucalyptus leaves or oil. Only those six years and above are advised to take cough medicine with eucalyptus. Pregnant and breastfeeding moms should not also intake eucalyptus.

However, eucalpytus is nontoxic when taken externally. Otherwise, it is toxic and must be diluted. So it is best to seek professional opinion from health care practicioners specializing in botanical medicine.
