The herb Perilla frutescens and the extract from the perilla leaf have been found in numerous studies to be effective for the treatment of allergies. In one study published in Experimental Biology and Medicine, perilla and one of its active ingredients, rosmarinic extract were found to ameliorate allergic inflammatory reactions including nasal and sinus congestion, and eye irritation.
In another study published in Phytotherapy Research, Japanese scientists at the Department of Kampo Medicinal Sciences, Hokkaido College of Pharmacy, found that perilla was more effective than a drug used for allergies. Another study published in the journal Food Chemical Toxicology showed that perilla oil had a beneficial effect on asthmatic allergies.
Perilla leaf or perilla leaf extract are available from many health food stores. Follow instructions on the package.
