“Generally speaking, the gland network is tasked with producing and distributing hormones throughout the body. As basic science shows us when hormones are released into the bloodstream, they greatly influence our body’s ability to grow and function properly, and so there’s a lot of effort put into making sure the 7 chakras, which effectively correspond to these glands, are in fact open and aligned. When they are not, health problems may arise.”
