Your aunt was right to connect the plant trilllium with childbirth, another name for it is Birthwort, since wort means "HERB", it is the birth herb. It was also given to women during chlidbirth. Usually a tea made with the bulb. We don't really know the actual effects of all the actions we take on earth, nor the causes. We might all be very suprised when we learn the true connections of events. I for one will keep an open mind, and only pick trillium when the need is dire. I have transplanted some from my forested property where they are abundant, to other areas of the yard, with a generious amount of root & soil, and little distrubance they do transplant. I had not read of the additional uses you mentioned so I am happy to learn of additional uses of this lovely flower.
