In a recent study at Japan’s Kyoto Prefectural University of Medicine, the herbal extract perilla oil shut down allergic reactions, soothing itchy eyes and sinus symptoms, plus erasing wheezy, asthma-like breathing problems in as little as seven days. Credit goes to perilla’s rosmarinic acid and luteolin, plant compounds that dampen inflammation, plus help destroy the abnormal white blood cells that kick-start most immune attacks. Look for perilla oil capsules in your health food store under brand names like Source Naturals and Life Extension. Concentrations can vary, so follow the package directions for dosage.
Bonus: Perilla oil is especially good at soothing itchy, bloodshot eyes -- a problem that plagues up to 90 percent of allergy sufferers, according to researchers.
