I want to add onto what Hmmm444 had discovered: Candida overgrowth is a major cause of hemorrhoid. That was an important finding. To check whether you have candida overgrowth in your body, look at your tongue in the morning. If it has a thick white coating and looks bloated that is a sign.
In TCM, that's traditionally a sign of internal dampness that is the cause of many diseases. It is said that the drying function of the body, called the "Spleen" is failing. Dampness is fertile ground for yeast to overgrow causing flatulence, inflammation and even bleeding. The latter are the body's attempts to rid of the fermentation that these bad bacteria produce. The dampness and candida overgrowth in the intestine also disrupt the normal functions of the bowels resulting in constipation. That's my theory after experiencing hemorrhoid for many years and now tackling it the right way.
Hmmm444 has offered valuable suggestions like cutting down on sugar, white wheat flour (SCD diet forbids it completely as it is the major cause of IBD/IBS), processed and acidic foods.
I want to add an important remedy: GARLIC. (Unless you are allergic to it, you should try it. As for allergy, I wonder if it is the effect of garlic working and perhaps one should go slow and build up the dosage slowly. )
I think garlic is not an ordinary herb but a living force in itself. It produces Allicin only when cut or crushed. Allicin is anti-bacterial and works even on bacteria resistant to the doctor's antibiotics. Garlic also has other numerous ingredients good for the body. This has been well researched by experts over the years.
Garlic kill off candia and dries up the dampness in the intestines. Peel 2 cloves of garlic and chop it into fine pieces. Leave it in the open for 15 minutes to allow the Allicin that destroy bad bacteria to be produced. After 15 minutes consume it and here's the TRICK on how to do it without problem. You see, even though I know for many years that garlic is very good for the body, I deprived myself of raw garlic because I found it quite impossible to eat it by drinking it with liquid because of its very pungent taste.
Now I am able to do so by SWALLOWING the chopped garlic with liquid. I usually take some food like a glass of unsweetened soya milk first; then I wash down the chopped garlic in several gulps. That was easy, my tongue did not get burnt by it. Eat 2 cloves this way, two to three times daily. Next morning when you check your tongue, the white coating would be not be there; that's a good sign. Your hemorrhoid inflammation would be improved and any bleeding due to water retention in that area would be remedied. One doctor even recommended inserting a garlic clove into the rectum at night. I hesitated to do that for a long time but when I tried the method, I found to my surprise there was indeed no or very little irritation.
To end, I think hemorrhoid, IBD, IBS are basically symptoms of the same problem - water retention and overgrowth of bad bacteria - but at different stages of development. I am also a sufferer of IBS for many years and when I use garlic and non-acidic and no-wheat diet, my problem improved. Especially with garlic the improvement has been dramatic.
I know everyone out there isn't going to like this, but hemorrhoids are symptoms of CANDIDA overgrowth. That's the reason that cleansing the area with apple cider vinegar is often effective - it balances the pH because although it's an acid, it has an alkalizing effect. Drinking apple cider vinegar also helps to alkalize your blood, but you need to eat other alkalizing foods too (and minimize acid forming foods) to experience true alkalization. So, another effective remedy that will not burn the way apple cider vinegar does, is one that also works for women's yeast infections. It was given to me by a conventional doctor and I modified it. The doctor told me that filling a capsule (which you can purchase at a pharmacy or at a health food store) with BORIC ACID and then inserting the capsule into the vagina will balance the pH and stop yeast infections. He said to do it every day that a yeast infection is present, and then once a week afterwards. Tou can buy boric acid at a pharmacy without a prescription. It's a powder. Since I have done this many years ago, I haven't experienced a single yeast infection (touch wood) and I've stopped using the capsules. Later on, I discovered that mixing the boric acid in coconut oil can be used for treating yeast AND hemorrhoids (mix it into a paste and store it in a small glass jar - I use extra virgin, organic coconut oil). The hemorrhoids you are experiencing are really just a kind of yeast infection in your anus. So, if you have hemorrhoids, you need to first look at your diet. Eliminate the easier forms of sugar - stop eating white flour and processed foods - spelt is a DELICIOUS substitute for white flour, and increase your intake of vegetables, particularly fresh. They will add bulk to push food quickly through your system. Drink lots of water, cut out pop and sugary drinks, and add a bit of fresh lemon to your water. Lemon juice will help to alkalize your system too. For fiber, grind a couple of tablespoons of flax seeds in a coffee grinder (I have one dedicated just for flax seeds) and mix with water. You can add a tiny amount of psyllium for bulk, but make sure it's organic, because psyllium is very highly sprayed with pesticides. Take a good probiotic, such as Garden of Life, FAITHFULLY, to repopulate the good flora in your system. Consider doing a gentle cleanse - one where you work up to only green vegetable juices and water for a few days (along with ground flax seeds for fiber). Also, take a good magnesium supplement to soften and regulate your stools. You will know when you are taking enough magnesium when you go number two several times a day but it's not liquid. Prune juice is an excellent addition too. A great magnesium supplement is Calm by Peter Gillingham. Please let me know how this works for you!
