I have this huge plant of Paracress, also called tootheache plant, and always chew the leaves while feeding the animals. Its very interesting. But I dont think it has any recreational possibilities. I cut my foot one day, a shallow cut but blood came, and mushed the leaves in my hand and wiped the juice in the cut. It did nothing but burn like fury. If anyone has imput on how to exstract the numbing chemical in it. I dont know waht taht is but yea. Thank you
