I don't think one is allowed to mention or flog companies or retail stores here so I will msg you.

Most natural food stores sell these products. I purchase direct from an online company. There are several reputable firms. Just do some homework.

A warning to look at the labels and make sure it is an Essential Oil and not a Scented Oil.

You may be deterred by the cost but remember you are only using drops at a time and thus they last a goodly long time.

My favourites are lavender and thieves for calming and peppermint and lemon for energizing.
