Hi @juy77, I thought I would post the link to the Mastcell360 site that you found useful so that others can read the information

Thank you, juy77! I recently flagged (saved) my latest email from Beth. Why? Part of the article was devoted to other histamine blockers that were new to me.

I have never had digestive problems before but am also taking digestive enzymes. All of this began after the Pfizer double jab!

Just reread your reply, juy.

If you have the time, please share why you cannot take DAO, H1 Blockers or H2 Blockers. Verrrry interested.

I am a "health nut" who learned the efficacy of supplements waaaaaay back in the early 1970s. That's when the older brother of my best friend steered me to B Complex (especially B12), Vitamin D3 and cod liver oil. May have saved my life. My dear, dysfunctional family included a bipolar/manic depressive mother (her fourth suicide attempt was successful), severely autistic brother and an alcoholic, wife beating, child molesting stepfather. My life circumstances had not changed but with those supplements I was better able to cope and ceased considering suicide.

Now I take dozens of supplements! Again, they may be keeping me alive since my diet is so limited. I had to cease taking some of them since they're high histamine. However, I get all the basic nutrients and more.

I have yet to add Holy Basil or Skullcap to my regimen. I will definitely look into both of those. I do take Stinging Nettle Leaf and Quercetin with Bromelain.

Via a company called something like Advanced Labs Food Intolerance, I learned I'm low in magnesium. Not surprising when my worst months included up to nine episodes of diarrhea per day. But I've yet to find the right magnesium that won't have a laxative effect. All the supplements in the world won't do me a bit of good if I can't keep them in my system long enough to be absorbed.

Thank you for reading this far. Genuinely interested to learn about you versus DAO and histamine blockers. I have a couple of mottos: God's Pharmacy First and Mother Nature Provides.

Very grateful!

Revisiting your post for good reason. Wondering how you're doing with the herbals for a VERY good reason. Recently learned that man-made antihistamines can be antagonistic toward choline of various forms. Choline deficiencies can be an indicator of future dementia! What a nightmare. In fact, a recent test indicated I am currently deficient in choline... Because of 18 months of diarrhea or because of the long-term use of antihistamines???

Very recently learned of other natural antihistamines. Have yet to research all of them. Some are part of my daily regimen for other reasons, my being ignorant of their antihistamine benefits. Here's the list with brief comments:

Forskolin (have to research)
Quercetin (been taking for years in a blend with Bromelain)
Astragalus (been taking for years for immune strength, didn't know it's antihistamine effect)
Vitamin C (no need to comment except that too much can cause "loose stools""
B. Longum (I assume this is a probiotic that's no to low histamine)
B. Infantis (I assume this is another no to low histamine probiotic)
Erythropoietin (Huh? Never heard of this one. Have to research.)
Theobromine (related to tea? I no longer use organic green/matcha tea in my morning shakes but do take EGCG daily)
Guarana (I know of it's energy boost--unbound caffeine that can be gently metabolized)

Now that I've learned the cognitive downside of OTC and Rx antihistamines, I would dearly love to imitate you. Oh, I do take Stinging Nettle. Will check into Holy Basil and Chinese Skullcap.

I apologize for failing to do my research first to share more meaningful info but wanted to share what I could ASAP.

Final note: Because of you, even with low histamine foods, I am freezing all leftovers IMMEDIATELY!

Wish I could thank you face-to-face! Clicks on a keyboard will have to do.
