Eucalyptus oil, also known as ‘Nilgiri tel‘ (Hindi) is one ingredient that can have far-reaching effects on our overall well-being. This amazing oil is obtained from the dried leaves of the eucalyptus tree. These sweet-scented leaves are steam-distilled to make the oil. This oil is a colorless liquid with a strong woody and sweet scent. Today, around 5% of the oil comes from Australia, while the remaining 95% is contributed by China.
