Eucalyptus oil is derived from the leaves of the Eucalyptus tree (Eucalyptus globulus or Tasmanian blue gum) native to China and Australia. It is known for its stimulating and antiseptic properties and is valued for its penetrating, camphor-like fragrance, similar to Vicks Vapor Rub, that opens up sinuses, fights colds, and is an expectorant and cough suppressant. It also has been used to relieve joint pain, muscular aches, and the swelling of arthritis. It is also an effective parasitic repellent.
Eucalyptus globulus oil has been shown to kill pain and help wound healing significantly when applied topically to sores and wounds. In addition, Tasmanian blue gum oil penetrates deep into the skin and is, therefore, a suitable carrier for transporting healing components, as found in lemon balm, deep into damaged tissue.
It can help speed wound healing by preventing bacterial infections. Eucalyptus oil is suitable for treating acne, infected wounds, ringworm, dermatitis, cuts, blisters, herpes sores, chickenpox, staphylococci infections, and shingles. Tasmanian blue gum oil can ease the pain from burns and can soothe painful insect bites.
Eucalyptus encourages new tissue growth when used on a sore or wound by increasing the supply of available cellular oxygen. It increases the rate of respiratory metabolism for skin cells, thus helping to oxygenate the skin cells directly, resulting in healthier skin. Research has shown that eucalyptus oil is an effective local immune modulator and will work to reduce the primary phase of inflammatory skin response by enhancing the action of gamma and beta-globulins.
