Tea Tree Oil: Benefits


Tea Tree is revered for its antibacterial, antiviral, antimicrobial, antiseptic and powerful antifungal properties.More recently, the scientific community has confirmed that Tea Tree Oil has tremendous medicinal benefits. It is a light yellow oil that has a scent similar to nutmeg, and it is produced by steaming tea tree leaves and then squeezing the oil out.

Tea Tree is used to treat athlete’s foot, burns, Candida, cold sores, corns, dandruff, eczema, insect bites/stings (or other itches), lice, nail fungus, psoriasis, respiratory infections, ringworm, chicken pox, sore throat, strep throat, thrush, warts, cuts, as an insect repellent. Tea Tree can be toxic when used internally, and it is best to avoid when pregnant or lactating. This essential oil can be used neat on the skin, but some people are sensitive to it.  To test if you have a sensitivity, try diluting tea tree in a carrier oil (i.e. sweet almond, jojoba, sesame, grape seed) oil before applying a small amount to your skin (avoiding the face and other sensitive areas to begin with.)

Studies have shown that Tea Tree Oil also treats respiratory problems ranging from common sore throats, coughs and runny nose to severe conditions such as asthma, tuberculosis, and bronchitis. The anti-viral properties of the oil fight many common infectious diseases such as chicken pox, shingles and measles, flu, cold sores and verrucae. It also strengthens the body’s immune system, which is often weakened by stress, illness, or by the use of antibiotics and other drugs.

Why are metals good conductors?


In metals there are large numbers of free electrons which transport major amount of heat and move from hotter part of the solid to the colder part transporting heat energy. e.g. In winter a steel chair appears colder than a wooden chair because steel being a good conductor of heat, when touched absorbs heat from the hand rapidly giving the feelings of coldness.


Metals are good conductors while gas and air are poor and bad conductors respectively. Hence:
•Two thin blankets are warmer as they enclose air in between
•A new quilt is warmer than an old one because it encloses more air
•Eskimos make double-walled ice houses and the air in between two ice walls does not allow heat to pass
•A thermos flask is made of double-walled glass bottles.
