Jewelweed (Touch Me Not).

This is almost an embarrassing post, but something that I am sure everyone has dealt with at one point or another.
I was on a backpacking trip with Tom, my partner for 7 years. Well I was terribly constipated. It was to the point of pain and I was miserable. As we were hiking, he gave me a few leaves off of a jewelweed plant and told me to chew on them. Mind you NOTHING I tried was working. I did as he suggested.
Within an hour, well…..I was no longer constipated! I have used this plant several times and it always worked well.Mind you it is perfect for Poison Ivy/Oak as well. The juice from the stalk placed on the affected area will ease the itch. I know of some people who take this and freeze it, making little ice cubes to use for poison ivy as needed.

Tannic Acid from Acorns

When leaching the tannic acid from your acorns, do not dispose of the water. It has many medicinal properties and you will be tossing out a gold mine of opportunity.

Store the water in a tight container in your refrigerator and use this for a mouthwash if you happen to get ulcers in your mouth. You can use this water as a skin wash for sores, cuts, etc. as well and it will help kill the bacteria causing infection and help heal the wound. You can use this water also as an insect repellent when spending time outdoors, it is great for insect bites.

Save the water from the 2nd and 3rd boiling to use as an enema for hemorrhoids.
