Can pineal cysts go away on their own? Would natural remedies work?

Don't worry, wise up. 1) There are no "natural remedies" for anything. "Ancient wisdom" is a myth. It's an indulgence of the ignorant. You can almost bank on it: Anything touted as a "natural remedy" by health hucksters is worthless. Malaria, snake venom, botulism, Ebola, all "natural." 2) Pineal cysts aren't clinically significant. They do nothing. They're just there. My advice: Find something else to worry about.
