For constipation, various herbal remedies work for both the colon -- and improving adrenals as they power the whole body function. It also helps to actiivate the bile flow.
Personally, I have used Dr Schulz's Intestinal Cleanser 1 and regularly get a BM even from his IC #2. http://www.herbdoc.com
- His info is also in line I think. I think.
I also benefit from Dr. Christopher's Herb Shop, his product for Lower Bowel but have to use more. This formula is also available in some health food store's as Nature's Way inexpensive brand Intestinal Cleanse Formula 2 (I think it is #2) -look on line for the Dr Christopher one and compare the herbs in the store bottles.
StanMar health food store in Midvale, Utah (near SLC) has Stan Malstrom ND's detox formula CAC that I found very healthful years ago when they had it in tablet form. It includes butternut bark to stimulate bile flow - so some places warn against using it of people have stones.
Aloe vera whole leaf gel helps - I drink Lily of the desert brans in gallon jugs, which tested good for me with my pendulum as well as muscle testing 7 it feels good internally. Aloe definitely helps my liver as well - I can tell because my eyes get brighter and clearer with more energy (Chinese medicine - Eyes are part of the liver system).
Fresh fruit helps - especially for some people oranges. I even benefitted from drinking mini-cans of orange, grapefruit & pineapple juice I took to work for a snack. Currently I like strawberries, grapes, pineapple. I personally never got BM improvements from dried fruits.
Carrot juice in large quantities can help, and especially spinach juice. See Norman Walker's book, Fresh Vegetable & Fruit Juices - a classic.
Even a lot more water helps. I often add a peppermint teabag or two to a gallon jug of distilled water and swig it thru the day. The peppermint is said to be good for the intestines & is anti bacterial.
For the adrenals, bith western herbs and Chinese herbs have helped me invcluding when I take the items mentioned I get a BM soon. My adrenals and Kidney yin and yang have been down on and off for years since I was in my 40's, either from a lot of physical exhaustion, illness or lfe stress.
Typically adrenal glandular tablets are recommended by chiropractors & naturopaths & I do find they give me more energy.
I also use Dr Christopher's Adrenal (and thyroid and pancreas) formula. Licorice is a standard herb for the adrenals & it is recommended to take the same amount of hawthorne for the heart if you do the licorice. It has herbs for other parts of the body, too. It works well for me. Lots of energy in various organs & more endurance.
I use Dr Christopher's Liver-GB formula as well and it relaxes me and therefore must be cleansing the liver as they say it does. They say it helps with liver stones but I have not yet looked into that personally. I use the blood stream formula as well and it does calm and stabilize the heart - and I add my own either powdered or whole hawthorne berries.
Oriental medicine doctors (OMD, DOM, Accupuncturist) use Rehmannia 6 typically for yin tonic but adding kidney yang to it helps. Since my yin has been drained (as well as my kidney yang), taking a good yin tonic formula is like charging the battery for my adrenal motor. The adrenals are part of the kidney yang system.
I'll try to answer any questions on this - I am not a doctor of any kind (More so computers & bodywork) but I have been ill for some time and all this (plus more raw food diet etc) helps. I do not have any vested interest in any of the items or resources I mention. I was constipated a lot for the first 30 years of my life, then got 18 colonics in 18 days & had just switched to a vegetarian diet. That also made a big difference.
