In 2006, the world con­sumed more than 3.5 bil­lion gal­lons of oil per day. A lot of that oil has caused envi­ron­men­tal dam­age and con­flicts between nations. But there is one type of oil that’s green, sus­tain­able, healthy, and–as far as I know–has nev­er been the ratio­nale behind a major mil­i­tary inter­ven­tion: tea tree oil.

Tea tree oil, explains the UWA Tea Tree Oil Research Group, is the essen­tial oil steam dis­tilled from the Aus­tralian plant Melaleu­ca alterni­fo­lia (unique to Aus­tralia and native to North­ern New South Wales). Tea tree oil is usu­al­ly clear to very pale gold­en in col­or and it exudes a fresh, cam­phor-like scent.

Kathi Keville of HowStuffWorks.com says this oil is often called a “med­i­cine cab­i­net in a bot­tle” and is “effec­tive against bac­te­ria, fun­gi, and virus­es and stim­u­lates the immune sys­tem.” Here are 20 ways to use this mag­i­cal for­mu­la for health and for the home.

But first, two impor­tant notes, cour­tesy of Sheila Shaigany:
*Make sure it comes in a dark glass bot­tle with a drop­per. This will pre­vent light from shin­ing in and reduc­ing the oil’s poten­cy.
*Do NOT ingest it oral­ly.
