While reading the latest post in the parasite cleanse forum, I think I found out why my worm is darkpink/red! From a quote from Hulda Clark:
" B12 is a beautiful rose colored vitamin. Some worms are actually pink from absorbing your B12! Giving B12 shots is the current clinical treatment for B12 deficiency. Killing Ascaris twice a week by zapping and taking B12 lozenges (see the Sources chapter) is a better solution."
