Especially women who are pregnant or want to become pregnant in the near future, be careful about consuming anything derived from pine needles. Yes, they are a good source for many vitamins and minerals, particularly vitamin C. The flipside is consuming enough pine needles in any form can cause miscarriage, even in farm animals. Farmers sometimes find a cow that has miscarried after chomping down on too many of them. Always check with a medical professional. I am not one, I just like learning about foraging.
