It sounds like they could be hookworms, but the only way to know for sure is to have them analyzed by a laboratory that specializes in parasitology.
If they are hookworms, your stool may be orange because they have been attached to your intestines, like little internal vamplires, sucking your blood. When they die off, and let go of you, they leave a raw spot that bleeds and comes out along with their mucous nesting material.
Marshmallow root will help heal those lesions and sooth your intestines. It may be in your Humaworm formula. Check to see. If not, you might want to buy some and take it.
You may want to reduce the dose. It won't hurt to go a little slower.
