Gut bacteria
It has been discovered that many human ailments are due to an imbalance in their gut bacteria. They are now feeding people with pellets that are screened faeces that come from people with "good" bacteria.
Some medical treatments are known to upset the patient's gut bacteria balance. The mix of bacteria can be very specific to each person. They are now "banking" some of the patient's own faeces before the treatment - so they can be used afterwards as pills to re-populate their gut.
