Stinging Nettle for Joint Pain Relief

Research suggests mixed and preliminary findings on stinging nettle for joint pain relief. The available evidence consists of a small randomized controlled trial and an uncontrolled pilot study, both limited by very small sample sizes and short treatment durations. The RCT, which tested topical nettle sting applied to the knee in older adults with osteoarthritis, found that both the nettle and placebo groups experienced similar modest reductions in pain, meaning no clear benefit over placebo could be established. The pilot study reported meaningful reductions in pain and mobility limitations using a multi-herb blend that included nettle, but because it lacked a control group and involved only 13 participants, it is not possible to attribute those improvements specifically to nettle or to rule out other explanations such as the placebo effect or natural symptom fluctuation.
