CheeZheng pain-relieving plaster (PRP) is a pain patch. It contains camphor and six different herbs.
CheeZheng pain-relieving plaster is used to:
Relieve aches and pain caused by strained or sprained muscle
Relieve aches and pain caused by arthritis
Talk with your healthcare providers before using herbal formulas. They can interact with some medications and affect how they work. For more information, read the “What else do I need to know?” section below.
Side effects of PRP on your skin may include:
Redness
Pain
Itching
Blisters
Do not use PRP on wounds or damaged skin or with a heating pad. Do not bandage tightly over the applied plaster. Avoid contact with eyes or mucous membranes when using the plaster.
For Healthcare Professionals
CheeZheng pain-relieving plaster (PRP) is a topical analgesic widely used in the Asia-pacific region and U.S. to manage musculoskeletal pain (1). It consists of camphor, Zanthoxylum bungeanum Maxim. (Hua Jiao), Lamiophlomis rotate (Benth.) Kudo (Du Yi Wei), Curcuma longa L. (Jiang Huang or Turmeric), Myricaria germanica (L.) Desv. (Shui Bai Zhi), Carthamus tinctorius L. (Hong Hua), and Oxytropis falcata Bunge (JiDou).
Clinical data are limited with most studies originating in China. A systematic review/meta-analysis found PRP to be associated with improvements in low back pain and function compared to diclofenac/NSAIDs (2). Notably, PRP did not increase the number of adverse events compared to medications.
Another systematic review/meta-analysis reported PRP to be more effective against osteoarthritic pain/function compared to NSAIDs, glucosamine, intra-articular corticosteroids, hyaluronic acid injections, or acetaminophen (3).
However, majority of the studies in the above analyses are limited by small sample sizes, lack of placebo control, and risk of bias. Methodologically rigorous studies are warranted to bolster the evidence.
Preliminary data suggest benefits of PRP in reducing chronic musculoskeletal pain in cancer survivors (4)(5). Larger trials are needed to establish efficacy.
Muscle pain
Arthritis
The bioactive compounds in PRP, such as diphenylheptanone, sesquiterpene, luteolin, and iridoid glycoside, may help suppress proinflammatory factor expression and improve substance P receptor (SP-R), c-Fos, and glial fibrillary acidic protein (GFAP) expression in neurons to alleviate central and peripheral hyperalgesia (6).
PRP has also been shown to reduce inflammation and inhibit nociceptive response in animal models, which in turn may help alleviate pain (7)(8). It also affected significant reductions in levels of proinflammatory cytokines interleukin (IL-1B), cyclooxygenase-2 (COX-2), TNF-alpha, and 5-lipoxygenase (5-LOX) in macrophages (9).
PRP can irritate mucous membranes, eyes, and broken skin, therefore avoid using on wounds or damaged skin or with a heating pad. Do not bandage tightly. Avoid contact with eyes or mucous membranes.
PRP may cause skin allergies, redness, itching, pain, and blistering (3)(10)(11)(12).
