Internal Castor oil 2x a week safe??

Hello.

I am currently recovering from mercury toxicity.

I have SEVERE colonic inertia. Aka my colon is paralyzed. My Gastro thinks it is an infection and i will be tyring a Fecal Transplant soon. 100g vit c does nothing. This is not your normal constipation so please do not tell me to try magnesium etc or more fiber. This is a rare case.

I am on andy cutlers chelation 3 days a week. As you can imagine, not being able to have any bowel movements without powerful laxatives or enemas is a problem when chelating mercury. The liver will get super burdened and i will probably get worse.

I have been following a modified gerson therapy, drinking about 2 quarts a day of fresh organic juice.

Twice a week i have been drinking castor oil 20ml in the morning, then do a chammomile tea enema 6 hours later. It gives an EXTREME purge and the smell is TOXIC. I feel so much better after it.

Gerson used these for cancer every other day for 3 months then taprered them off.

My concern is the gut flora damage. Studies show that colonscopy flushes cause gut flora damage.

But i do not know what is worse. Severe constipation when trying to detox mercury, or purging the colon flushing toxins but damaging the flora?

here are the studies.

I would prefer to do coffee enemas to keep the liver detoxed but they gave me quite severe colon inflammation so i was forced to stop. However i would like to try pure caffeine enemas to see if i can get the bile flow effects without the inflammation.
