Arthritis treatment with topical herbal remedies
A number of topical herbal remedies (those that are rubbed into the skin) are sometimes used in the treatment of arthritis. Some have skin-warming ingredients, while others may have more of a painkilling or anaesthetic effect on the skin.
Capsaicin
Capsaicin, a pungent ingredient in red peppers, is available in cream form which can be bought over the counter at pharmacists. The creams are recognised as being an effective addition for pain associated with both osteoarthritis and rheumatoid arthritis. Investigations in recent years have revealed that capsaicin acts selectively on nerves involved in pain and inflammation.
The first application of capsaicin can cause pain, local reddening and swelling, but then the nerves become insensitive to further stimulation (including capsaicin itself). Repeated application of the capsaicin appears to desensitise the nerves, giving pain relief.
Nettle
Plant extracts from the leaves of stinging nettle are sometimes used to relieve the pain of arthritis. It is not known how stinging nettle leaves work, but they are believed to contain substances which might affect pain perception and transmission at the nerve endings. Recent evidence has also suggested that the active ingredient in nettle extract may inhibit inflammation in autoimmune diseases such as rheumatoid arthritis.
