CBS2's Mary Calvi reports that, in its pure form, pure gum spirit of turpentine was once used as a form of medicine centuries ago. Today, it's back as a controversial new wellness treatment.

Azmyth Kaminski is a healing consultant who takes it as an internal cleanse.

Pure gum spirit of turpentine is a controversial alternative treatment for stomach or intestinal issues like parasites or yeast infections.

The therapy is unusual and considered by many experts to be questionable, but there are believers who ingest it by saturating and chewing on sugar cubes. Actress Tiffany Haddish touted turpentine's benefits in a recent article, saying "everything felt so much better, clarity wise."

Kaminski documented his own turpentine experience on YouTube.
