Hi all! I'm treating hydrogen sulfide SIBO after realizing my profuse bleeding was caused by sulfur poisoning back in 2018. Using oregano oil but it's causing constipation. I have used castor oil hexane free as a one time laxative before and it worked wonders. I would never use it more than once in a 3 month period but I used it before I knew I had H2S sibo. Is it safe for this SIBO? is it low sulfur? I know H2S sibo doesnt do well with fats or oils but this does have antimicrobial properties too. Can I use it once? I'm backed up due to treatment and would prefer something natural. Magnesium oxide is another option but Im afraid it might be too alkalizing for my low stomach acids which could exacerbate other bacteria in gut and H.Pylori. thanks.
