A Homeopathic Arnica Patch for the Relief of Cellulitis-derived Pain and Numbness in the Hand

Objectives: Arnica montana, belonging to the Compositae family, is a plant with a longstanding tradition of relieving pain and/or inflammation in muscles and joints and may thus represent an alternative to nonsteroidal antiinflammatory drugs, which are often ineffective or lead to a number of adverse effects. A homeopathic arnica patch (3X dilution according to the Homeopathic Pharmacopoeia of the United States) was developed to alleviate pain symptoms in the back and neck muscles and joints.

Case Presentation: The present case report describes the treatment outcome after administration of the arnica patch in a 55-year-old female patient with pain in the right hand and numbness in the fourth finger after cellulitis in the palmar area. The cellulitis was treated with antibiotics, but pain symptoms remained at 7 points on a 0-to-10-point visual analog scale (VAS) for pain despite intake of oral ibuprofen and oral and topical application of an arnica-containing complex homeopathic ointment. Ten arnica patches were dispensed to the patient. She cut the patch into strips to cover all painful areas of the hand and applied them at night. After 3 days, she reported a substantial decrease in pain symptoms (VAS = 1) and a marked decrease in numbness and in the size of a tender nodule on the third metacarpal area. Moreover, the patient was able to sleep through the night without being awakened by the pain. The symptoms declined further during the next 2 days.

Conclusion: This case demonstrates that after a relatively short period of time, the administration of the arnica patch on the hand provided a marked reduction of pain and recovery of functionality of the hand.
