Olive oil is a base oil, which is mainly used to dilute pure essential oils with high concentration. If you want a full-body massage, you'd better use compound essential oil, which is a mixture of pure essential oils and base oil. Using olive oil alone can't achieve the effect of massage. If you have pure essential oils, you can do it yourself. For the specific preparation method, you can search Baidu Library's notes on essential oil preparation, which are described in detail. I hope I can help you.
