The size of a pea, the pineal gland sits right in the centre of the brain, behind the pituitary. It is a pine cone shaped endocrine gland, responsible for melatonin production in the body, which you probably know regulates the sleep-wake cycle, as well as some serotonin production. But more than that, it is known as the inner eye or the third eye. It's our inner vision, our own unique perspective on the world. Mystics know that through meditation, we can strengthen that third eye vision and our own insight. The plant foods in this section have all been used by cultures across the world to either detoxify and decalcify this important gland, or to support it and strengthen your access to the mystic realms.
