Understanding How Capsaicin for Peripheral Neuropathy Works

If you wonder why your mouth burns after eating chili peppers, you can attribute the feeling to capsaicin. It is a chemical compound found in chili peppers that gives them their distinctive heat or burning sensation. While we may think of capsaicin for its contribution to “spicing up” foods, the ingredient is a well know pain reliever. It binds to a receptor in the nervous system called TRPV1 that detects internal or external sources of heat. You find TRPV1 in the brain, peripheral nervous system, bladder, blood vessels, and other areas. [1]

When capsaicin activates the TRPV1 receptor the brain interprets the signal as heat. This is why spicy foods feel like they are burning, although there is no physical heat. In response to the heat sensation, the body feels like it needs to cool down, so that it responds with:[2]

·         Sweating

·         Flushed skin

·         Watery eyes

·         Runny nose

·         Increased heart rates

·         Signature mouth burn

Bottom line is that capsaicin creates a neurological response, not tissue damage. In addition to peppers, you will find the compound in oregano, cinnamon, and cilantro. Hot peppers have a higher concentration of capsaicin than these other spices. [3]

Capsaicin health benefits

Among the key health benefits of capsaicin are:

Pain relief: Blocks pain signals to provide relief from arthritis, muscle, and joint and neuropathy pain.

Boosts metabolism: Helps to burn calories by increasing thermogenesis, which is the generation of heat in the body, which affects metabolism, calorie expenditure, and weight loss.

Cardiovascular health: The anti-inflammatory properties of capsaicin may be what experts believe contribute to the heart-health benefits of capsaicin. A study conducted over three months found that capsaicin reduced the risk factors of heart disease in adults with low HDL (the good cholesterol) levels. [4]

Gut and digestive support: Stimulates gastric juices and the production of enzymes. Used to manage discomfort in gastrointestinal conditions.

What is peripheral neuropathy

Peripheral neuropathy indicates a problem within the peripheral nervous system. When peripheral nerve cells, called neurons, become damaged or destroyed, neuropathy disrupts the way they communicate with each other and the brain. Symptoms include burning, numbness, shooting pain, tingling and muscle weakness or atrophy. Peripheral neuropathy typically affects the feet and legs and sometimes affects the hands and arms.

Peripheral neuropathy is common among diabetics. The National Institute of Health (NIH) National Institute of Diabetes and Digestive and Kidney Disease (NIDDK) estimates about one-third to one-half of people with diabetes have the condition due to high blood glucose or blood sugar.[5] That’s because high blood glucose or blood sugar and high levels of fats in the blood from diabetes can damage nerves and the small blood vessels that nourish nerves, leading to peripheral neuropathy.

Since peripheral neuropathy can cause numbness, if you have diabetes, you might not feel a foot injury, cut or even a blister that could result in an ulcer. Foot ulcers are a considerable problem for people with diabetes often leading to hospitalization.

Research on capsaicin for neuropathy

A systematic review published in 2022 looked at the use of capsaicin 8% patch versus oral neuropathic pain medications for the treatment of painful diabetic peripheral neuropathy. The review found most of the summarized literature indicates that topical capsaicin (0.075 %) cream, when applied to the painful areas for approximately 8 weeks, can reduce pain, which may lead to clinical improvements in walking, working, and sleeping in patients with painful diabetic neuropathy.[6]

Another research review published in 2025 found that capsaicin can provide prolonged relief from pain in various neuropathies. Researchers reported that one proposed way is capsaicin’s ability to cause degeneration of hypersensitized nerve tissue and stimulate regeneration of healthy nerve fibers. They found capsaicin is effective for treating both diabetic and non-diabetic neuropathic pain. As a topical treatment, researchers concluded that there are fewer systemic adverse events and therefore topical capsaicin for neuropathy is an attractive option in the treatment of peripheral neuropathy.[7]

And another cohort research study on capsaicin for diabetic peripheral neuropathy used data from the German Pain e-Registry (GPeR) to evaluate the high-concentration capsaicin topical system for treating painful diabetic neuropathy of the feet. Thid study of capsaicin for neuropathy in feet included over 365 patients. [8]

The study of capsaicin for neuropathy in feet found that repeated treatment with high-concentration capsaicin topical system treatments significantly reduced average pain intensity, improved sleep and quality of life, reduced affective distress, and decreased medication used simultaneously in patients with painful diabetic neuropathy in feet. The study on capsaicin for neuropathy in feet observed  further improvements with ongoing treatments.

Topical capsaicin for neuropathy

Topical capsaicin for neuropathy can be found in over the counter (OTC) creams to ease tingling and nerve pain. The skin absorbs the creams to soothe, nourish and reduce pain and discomfort. Such creams typically include ingredients that hydrate the skin and offer a cooling sensation. They offer relief from pain while also supporting overall foot health.

Menthol is another ingredient found in many OTC topical capsaicin topical for neuropathy creams. Menthol is a chemical found naturally in mint plants but also can be produced in a lab. It seems to activate a channel involved in regulating sensory neuropathic pain.^[9]  Menthol creams work fast to provide relief.

Products such as EASE-Z Pain Relieving Foot Cream, Diabetic Safe, provides targeted relief from neuropathy symptoms. The OTC product contains capsaicin and menthol to block pain signals and reduce inflammation. EASE-Z Pain Relieving Foot Cream also features Zinc Acetate, an ingredient recognized for its powerful benefits to protect the skin and enhance the healing of minor wounds and sores.

To help nourish skin and deliver long-lasting relief from dry, cracked, itchy discomfort, EASE-Z Pain Relieving Foot Cream also includes as one of its ingredients Shea Butter, known for its rich moisturizing properties. The result is a fast-absorbing non-greasy foot cream that delivers lasting pain relief to improve daily quality of life.
