Who Should Avoid Moxibustion, Cupping and Gua Sha

Start here

Moxibustion (burning a dried herb near the skin), cupping (suction cups on the skin) and gua sha (scraping the skin until it marks) are hands-on practices from Chinese medicine. This page lists who is commonly advised to avoid them or ask a doctor first. It is information only. It gives no instructions for doing any of them yourself, and it does not replace advice from your own doctor or pharmacist.

An honest limit first: Proper evidence not found for a single, trial-based contraindication list for any of the three. I checked NCCIH, PubMed reviews and consumer health pages from a major hospital system. The cautions below come mostly from consumer health guidance and from reports of harm, not from controlled studies that tested who should be excluded. Treat them as sensible warnings, not as a complete list.

Cupping

NCCIH says cupping can cause persistent skin discoloration, scars, burns and infections, and may worsen eczema or psoriasis. [1] Rare severe problems include bleeding inside the skull after cupping on the scalp and anemia after repeated wet cupping (where the skin is pierced). [1]

Cleveland Clinic's patient page advises against cupping in pregnancy because so little is known about its effects. It also lists anemia, a pacemaker, bleeding disorders such as hemophilia, blood clotting problems or a history of strokes, cardiovascular disease, skin conditions such as eczema and psoriasis, and epilepsy. [2] That is one organization's advice, not a trial result. A review of cupping trials in musculoskeletal care found the rate of adverse events very low, but those studies were not designed to test people with these conditions. [3]

Gua sha

Gua sha intentionally raises small skin bleeds (petechiae) and bruising. [4] Cleveland Clinic says it should never be done over irritated or inflamed skin such as rashes, wounds or sunburn, and that it may not suit people who take blood thinners, are having chemotherapy, are pregnant, have circulation problems, diabetes, or a skin condition like eczema or psoriasis. [5] I found no trial that tested these exclusions. A review of gua sha for perimenopausal symptoms found only six trials, most of low methodological quality. [6]

Moxibustion

A systematic review of the medical literature found allergic reactions, burns and infections as the most common problems, and said the true rate of adverse events is not known. [7] The same review reported premature birth, early rupture of membranes and bleeding in pregnant women in moxibustion reports. [7] Smoke discomfort, blistering and flare-ups were also reported in trials. [7] Pregnancy and breathing or skin problems are reasons to talk to a doctor first. Details are on the Moxibustion page.

Hygiene and marks

Cupping equipment shared between people without sterilization can spread bloodborne infections such as hepatitis B and C. [1] Cupping marks should be explained to health care providers so they are not mistaken for signs of physical abuse. [1]
