I swear by Helichrysum for its restorative properties.
I love using citrus essential oils in my diffusers and including them in my cooking.
Adding grapefruit essential oil makes a wonderful addition to many fruit drinks. I also love adding several drops of citrus essential oils together in a diffuser for an uplifting aroma.
I always use therapeutic grade essential oils in very small amounts when ingesting them. Look for the companies that have supplemental facts on the labels of their essential oil bottles.
