MARJORAM (ORIGANUM MAJORANA)
Marjoram oil can be used for easing muscle aches and stiffness along with helping to heal bruises and joint sprains. It is a good choice for topical use for those with fibromyalgia, which is a form of arthritis. It helps with pain but also alleviates muscle tightness. Avoid marjoram essential oil if you have epilepsy.
PEPPERMINT (MENTHA PIPERITA)
Peppermint contains analgesic compounds that reduce pain and inflammation. Like lavender, it can usually be tolerated on the skin in its neat form (undiluted) to help reduce pain. A little goes a long way as this oil leaves an intense cooling sensation on the skin. Use one drop and massage into painful or inflamed joints. Wash hands immediately and avoid eye contact.
Make sure you select high quality, pure, undiluted essential oils. While you may end up diluting the oils yourself, most of the oils on the market are diluted in less-than-desirable oils. High quality oils cost more than the cheap varieties on the market but are worth the increased price. Many cheap varieties can also contain synthetic versions of the oils, which offer no therapeutic value and may actually be harmful. But, worse than that, many cheap oils are adulterated with solvents used during the extraction process or toxic pesticides used in the growing process of the herbs from which the oils are extracted.
After diluting the oil in carrier oil, always conduct a 48-hour patch test on a small inconspicuous part of your skin to determine whether you have any sensitivity to the essential oils.
