Ayurvedic or essential oils may not contain chemical ingredients, but you need to be careful about how you store such oils in order to extract maximum benefits from them. You must store essential oils in glass jars or bottles that are either navy blue or amber or in any other dark colour. A dark coloured glass container is preferred in order to protect the essential oils from harmful UV rays. The latter can tamper with the therapeutic properties of oils. Do not use plastic bottles as some highly concentrated essential oils can prove to be corrosive when they come in contact with plastic containers.Heat and moisture can also have an adverse effect on the highly beneficial properties of essential oils. So keep the containers away from sunlight - put them in a cool, dark place.The best way to store essential oils is to put them in a wooden box. So invest in one and save your essential oils from losing their therapeutic powers.
