I use them as topical medicines (wounds, bug bites, bruises, on myself, my child, and animals), hair care, skin care, beauty product, immunity boosting additives to drinks and food, I use them as pest control, antibiotics (antimicrobial, antifungal, antibacteria, antiseptics, astringents), mood boosting elements as a perfume or even as aphrodisiacs (going on a hot date!) They can be antinflammatories topically or orally, and can aid in times of sicknesses. Some have pain releif properties for many all issues including mouth issues like teething infants. Decongestants. Laxatives. Room sprays. And surely other uses i am not thinking of.I choose to use oils like olive or coconut generally to mix when needed.
