Though research and other studies show that capsaicin has several benefits in enhancing metabolism by relieving topical pain, burning fats, and minimizing insulin spikes in diabetes, it can also cause a stinging or a burning sensation on the skin. Suresh and Srinivasan, (2010) administered capsaicin by oral gavage at a dose of 30 mg capsaicin/kg body weight in Wistar albino rats [35]. Chaiyasit K, Khovidhunkit W, Wittayalertpanya S. Pharmacokinetic and the effect of capsaicin in Capsicum frutescens on decreasing plasma glucose level. The generation of novel capsaicin-mimetics and improved drug delivery methods will foster the hope of innovative applications of capsaicin in human disease. showed some promise in the treatment of rheumatoid arthritis and osteoporosis. Capsaicin functions as a high affinity agonist of the TRPV1 receptor [4]. Experiments also showed that this substance lowers the blood pressure of rats that are prone to hypertension. also help prevent prostate cancer. Fang JY, Hwang TL, Huang YB, Tsai YH. The authors suggest that the lack of outcome measures may have been due to irritation and pain caused by the placebo patch.

The method by which the pain is reduced is not yet fully understood by researchers. Although this usually disappears after the first several days, it may last 2 to 4 weeks.

Burning sensation and skin irritation are the most common side effects of capsaicin. Capsaicin does not cause chemical burns or actual tissue damage, despite the fact that it causes pain. The combination of erbium:YAG laser treatment and ultrasound along with iontophoresis increased the skin permeation of nonivamide relative to vehicle-treated controls.

So, how long does this potent substance stay active on surfaces? The concentration of capsaicin in the plasma of patients 60 minutes after application was about 1.38 ng/ml [28]. Transdermal iontophoresis has been investigated in conjunction with other physical enhancement techniques such as low frequency ultrasound and erbium:YAG (yttrium-aluminum-garnet) laser to increase the transdermal delivery of nonivamide [50]. In severe conditions such as eye burns, topical ophthalmic anesthetics can do the job.
