ESSENTIAL OILS: Always know the properties of any essential oil you're using and know the contradictions, such as not using an oil when pregnant, breastfeeding, on infants or children or those who are immune-suppressed, etc. Some oils have lingering after-effects such as increasing the likelihood of getting sunburn if you go into direct sunlight after using them. Read all of the labels, warnings and directions accompanying each essential oil. It is also important to know of any allergies before using, which can be done by using a skin patch test or through knowing that you're allergic to the plant source in some other form.
Hydrotherapy: If you have high, or low, blood pressure, a bath that is too hot may cause problems. Always cool down slowly after a hot bath. Allow the water to cool or add cold water slowly to return your body temperature and circulation to normal
HERBAL REMEDIES: Some herbs, such as comfrey and ephedra, can cause serious harm. Some herbs can interact with prescription or over-the-counter medicines. If you are thinking about using an herbal medicine, first get information on it from reliable sources. Make sure to tell your health care provider about any herbal medicines you are taking.
