Perilla seeds (Nei Lieh): Nei Lieh is a herb which belongs to mint family, Lamiaceae. The oil extracted from Perilla leaves is rich in omega 3 fatty acids. The plant overall resembles the stinging nettle, though the leaves are somewhat rounder. The flowers bloom in August-September and by November, the flowers become dry and the seeds are harvested. Nei Lieh is not the same as what is known as ‘white sesame’ in the rest of India.
