A new South Korean study has shown that injection of a traditional Chinese herbal extract into acupuncture point could have both an anti-inflammatory and an immune-regulatory effect on bronchial allergic asthma. The herb used was perilla seed; injection is a therapeutic technique combining both acupuncture and herbal treatment.
Perilla seed has been used to treat respiratory diseases in Chinese medicine. The leaves of perilla have previously been shown to have a suppressive effect on allergies.
Recent studies have shown that perilla seed polyphenols regulate allergic diseases by 5-lipoxygenase inhibitory activity, along with the suppression of histamine release from mast cells.
