Since using kratom I have noticed some major improvement in my digestive process. Due to my health problems I tend to have poor digestion in general and food moves a little too quickly through my digestive tract. Kratom has drastically improved my assimilation process. I have also become very regular. (in digestion only, he he)
I attribute the improved digestion in part due to the slowing down of peristalsis, but also to the bitter quality of the herb. Bitter herbs are known to stimulate the flow of digestive juices, release of insulin and glucogon, as well as the release of bile. The potentiating herbs I use in combination with kratom also aid in the digestive process.
