A poultice made from Plantain (plantago major) is effective at relieving boils, blisters, and bug bites. It grows everywhere in North America & stays green most of the year. Barring any pesticides or other pollutants, the leaves are safe and entirely edible, however most wild animals and insects are not particularly partial to plantain so you should not have much trouble finding enough intact leaves. A simple cure from an adaptable plant to make a true home remedy. Recommended to me by a naturopathic doctor, this little fix has never failed.
Step 1: Find Plantain
Finding the plant can be very easy or very difficult depending on where and when you're looking... It often grows in sidewalks or along driveways where the grass meets gravel or concrete. If you live anywhere in Canada or America, the best place to check is often your own front yard. Don't confuse it with a Dandelion or other small weed.
