Chamomile’s anti-inflammatory and antimicrobial properties are comparable to those of painkillers, according to a new study by scientists from the United States and Japan. The results of a large meta-analysis were published in the medical journal Pharmaceutical Biology.

The authors analyzed data from 11 randomized clinical trials in which chamomile-based preparations were used to treat mucosal inflammation, oral infections, and gastrointestinal diseases. Chamomile extract significantly reduced pain, swelling, and inflammation, while accelerating tissue regeneration. The effects were statistically significant and comparable to those of nonsteroidal anti-inflammatory drugs (NSAIDs) — but without their characteristic side effects.

Chamomile showed its highest effectiveness in treating mucositis — inflammation of the mucous membranes that often occurs after chemotherapy or radiation therapy. The researchers attributed the plant’s healing properties to its active compounds, particularly bisabolol and apigenin, which help regulate inflammatory cytokine production and promote tissue repair.

According to the study’s authors, chamomile could become a safe and affordable alternative for managing chronic inflammation and may also be effectively used in preventive and cosmetic products.
