Peter is also noted for being the first non-indigenous person to use and write about 'sapo', the secretions of the Phyllomedusa bicolor frog, which are burned into the skin by the Matses Indians. His record of that use has opened the door to Western science with regard to utilizing amphibian peptides as possible medicines for human use. He has also worked with the American Museum of Natural History and collected medicinal plants from the remote Yivari river for Shaman Pharmaceuticals.
