Kapoor Kachri oil is an essential oil extracted from the roots and rhizomes of the Hedychium spicatum plant, also known as Kapoor Kachri. It is a yellow or brownish liquid with a woody, spicy and slightly sweet aroma. It is commonly used in traditional Indian medicine as a natural remedy for respiratory issues, digestive problems, and to improve appetite. It is also used in perfumery as a base note to add a woody and spicy aroma to fragrances, and in cosmetics as an ingredient for skin care products. It is considered safe for use in personal care products when used in appropriate concentrations, but it should be used with caution as high doses may be toxic. It's also recommended to consult with a qualified healthcare professional before using it.
