Tea tree oil is an excellent antiseptic, anti-bacterial, anti-viral and antifungal substance. A few drops of tea tree oil can kill fungal infections as well as help in healing. It is also a very effective tool in getting rid of any kind of lice infestations. It will help in taking care of common ailments such as dandruff and flaky scalp. It can also take care of acne, ulcers, minor cuts and scrapes, sore throats and common boils. It is one of the few oils that can be administered for almost any ailment. And the best part is that it has absolutely no side-effects. A word of caution: it must not be given in any form to infants or small children, as it may cause more harm than good, because it is highly concentrated.
With reference to your second question, black spots on the face can be dealt with in many ways. In order to lighten the patches on your skin, mix a few drops of lime juice and olive oil and apply. Lime juice will bleach the patches naturally and the oil will retain moisture and retain the quality of your skin. You must also exfoliate your skin once a week. You can make a natural exfoliating lotion with dried and powdered orange peels mixed into enough milk cream (for oily skin) or yogurt (for dry skin) to give it a pasty consistency and rub this into damp skin. Aloe vera gel is also a highly effective remedy for lightening dark patches.
