Yucca as an adsorbent

Charcoal and Chloryphyll are the most mentioned adsorbents with regards reducing fecal odors from stools (although there are anecdotal posts on forums about chloryphyll doing the opposite), the other lesser mentioned adsorbent is Yucca. This is often added to pet food with the intention of reducing odor. Like the other gut adsorbents, it binds to chemicals in the gut, effectively neutralizing them.

Unfortunately, at this stage in the understanding of bloodborne odors like fecal body odor, none of the above can be recommended with confidence, other than to inform you of the adsorbent choices. A good mindset, if you are reading this in the form of advice, would be to expect them to fail.

Whats the difference between absorbent and adsorbent ? : http://www.integrityabsorbents.com/content/abvsad.php
The difference seems to be, an absorbent acts like a sponge, whereas adsorbents bind at a smaller chemical level. Most water filters are charcoal-based.
