Cough and Cold

• Traditionally, tea tree leaves were steeped in hot water to create a healing infusion, the vapors of which were inhaled to alleviate chest congestion. This "tea" (from which the tree gets its name) was consumed by the Aborigines to cure sore throats, coughs and other cold symptoms. According to Heather Boon in her book "The Complete Natural Medicine Guide to the 50 Most Common Medicinal Herbs," use of this effective herbal remedy was adopted by the earliest European settlers to Australia.
  
  

Fungal and Bacterial Infections

• Today, tea tree essential oil is applied topically to treat fungal and bacterial infections of all kinds. According to the Mayo Clinic, tea tree oil contains terpinen-4-ol, a compound which may account for its antimicrobial qualities. Tea tree oil is used to make creams and salves to treat ringworm, athlete's foot and yeast infections, as well as cuts, burns, scrapes and insect bites; as such, it is a useful substance to have on hand in one's first aid kit.
