Recently I was looking online for some information that family member needed about whether it was safe to take melatonin when you were on an antidepressant. I was pretty sure that they should not be taken at the same time. I groaned when I saw the answer that someone had posted to this particular question on a message board. The answer was, "Melatonin is herbal, so it’s safe to take it with anything."
Herbs are considered safe by many people, under any circumstances, because they’re natural. But natural doesn’t automatically equal harmless. Almost anything natural can be toxic if not used appropriately. Sunlight is natural, but too much of it can give you a sunburn, or skin cancer. When I was a few weeks away from my wedding, I thought that I’d make sure I didn’t come down with a cold, so I took high doses of Vitamin C every day. I won’t go into details, but suffice it to say that I spent a lot of time in the bathroom before I wised up and settled for taking a multivitamin instead.
