Internal usage of Arnica is limited to homeopathic preparations which are available at health stores or from health practitioners. A topical combination of Arnica and St. John's Wort, like AcheAway , provides surprisingly effective relief from aches and pains. Meadowsweet and Willow Bark are two herbs that both contain salicin. These herbs are anti-inflammatory and analgesic. Like aspirin they may be taken internally or applied externally.
Essential oils are highly concentrated extracts that can greatly enhance any pain management system.
They are only used externally and must be diluted in a carrier for application to the skin. Many are highly aromatic. Camphor essential oil reduces pain, inflammation, and swelling. It is specific for skin, joint and muscular inflammations. Eucalyptus essential oil is specific for aching muscles and arthritis and also is anti-inflammatory.
