Thanks for your informing me a bit on Cascara Sagrada. I like to learn
about milder bowel cleansers. I’m a novice!
Some of the most prevalent herbs in his product, i read are:
Quassia - an anti-parasitic herb.
Caprylic Acid - an anti-fungal fatty acid.
Pau d'Arco - an anti-bacterial agent.
They could be too strong for him without an initial, bowel cleansing step, (as you
suggested. It makes sense to me.
These discussions are good to try to narrow down reasons for such distress.
