There’s a plant that grows naturally near poison ivy that cures it before a rash begins!

Jewelweed is an invaluable plant. It is a virtual panacea for skin irritation. It is common and widespread, as well as being easy to recognize. The stalk is succulent, translucent, and unbranched. Its leaves are roundish and notched; very distinguishable from other leaves. The Jewelweed stem is hollow. It is powdered with a pale blue-green, waxy bloom and partitioned by nodes. The plant grows up to five feet tall. It branches towards the top and toughens with age. 

A clear, watery liquid is inside its leaves, especially in its nodes. The Jewelweed is water repellent. Therefore after it rains, the plant is covered in jewel looking drops, accounting for its name. When jewelweeds are submerged in water, the underside of the leaves turn silver. In the spring and summer the jewelweed blooms yellow flowers with three petals. 

Jewelweed cures a number of ailments. Its juices can stop mosquito bites from itching and swelling if applied for 15-20 minutes after being bitten, along with wasp and bee stings. Jewelweed is also good for warts, bruises, and fungal skin infections like athlete’s foot and ringworm. 

It can also help with minor burns, cuts, eczema, sores, and acne. Jewelweed often grows near poison ivy and can eliminate a rash occurring from poison ivy when applied to the area.
