A natural health supplement of lemongrass and ground moss has been found by Lisa Ishimine, a teacher at Mission San Jose High School in Fremont, who previously suffered from severe bipolar depression. Depression can be a debilitating mental illness for many people, and Ishimine, a former victim, wished to find a way to save others from the same fate. Years of research went into various natural supplements, from probiotics to kale to herbal remedies, but most, if not all, had adverse side effects.
