Yes, bitters help with digestion and also flush out the liver. If you want to use these look for the alcohol-free type, and be sure to drink a LOT of water with it. Just use half a dropper full dropped onto the tongue before or after meals.
Dysbiosis is caused by an imbalance of beneficial bacteria in the intestines. Eating foods that build the flora (colonies of beneficial bacteria) will of course replenish the bacteria. The foods include kefir, homemade yogurt, sauerkraut, and apple cider vinegar. In addition, high counts and strains of probiotics will help to replenish the flora. Eating foods that are defined as ďprebioticsĒ will feed the beneficial bacteria allowing them to thrive and multiply. These include asparagus, avocados, endive, onions, garlic, chicory, and artichokes, especially Jerusalem artichokes. Prebiotic herbs include burdock root, yucca root, cinnamon Twig, rosemary and dandelion root.
