I have a couple questions regarding constipation. Herbal Therapeutics offers a constipation long infusion of marshmellow, dandelion root, and valerian. how long is it possible to take this for? a family member is currently using metamucil daily to aid in semi-regular bowel movements and looking to move away from this method. would the infusion offered be the best option here, or a tincture? this person also has a stressed complex, which I believe is part of their digestion issues. this is a long standing issue where I would love to be able to offer support. thanks for your time on this!
