Here's a link to the full-text of an article that lists some drugs and supplements that are mast cell stabilizers.  (The excerpt is taken from page 167.)

Quote:

It has been suggested that stabilization of mast cells
may be a key mechanism to protect the gastrointestinal
tract from injury (Karmeli et al., 1991; Eliakim et al.,
1992; Hogaboam et al., 1993; Whittle, 1993; Low et
al., 1995; Kalia et al., 2000; Kiraly et al., 2000; Ruh et
al., 2000). Few molecules are known to possess both
mast cell stabilizing and gastrointestinal cytoprotective
activity. These include zinc compounds (Cho and Ogle,
1992), sodium cromoglycate (Cho and Ogle, 1992), FPL
52694 (Cho and Ogle, 1992), ketotifen (Cho and Ogle,
1992), aloe vera (Ro et al., 2000), certain flavonoids
such as quercetin (Middleton et al., 2000), some sulfated
proteoglycans such as chondroitin sulfate
(Theoharides et al., 1999; Hori et al., 2001) and
dehydroleucodine, a sesquiterpene lactone (Giordano
et al., 1990; Penissi et al., 2003a,b).

Your comment was very interesting to me. I don't have bowel trouble or atleast too much. But your talk about glucosamine & MSM is interesting. I had taken large amount of both for about 5 years before I came down with SM. I thought it might have been the shellfish allergy but maybe it was the sulfate angle, as I am now Nasids intolerant and had trouble finding an antibiotic before I found clarithromyacin that I could take wen I have a sinus infection. My daughter who has RA has real sulfate problems. So you might have hit on the mystery that I was looking for.
Thanks

SM with heavy cuteanous issues, ie. skin pain & sensitivity. The only test that I've had is the tryptase level of which mine runs in the 16-18 range which is kind of normal for a leaker with a ckit mutation. My doc said at this point either a bmb of skin biopsy isn't necessary, because of my symptoms. My seronotin test came out on the low side of normal but normal. So since my tryptase is inflated it's easy for them to give me a SM diagnosis. With yours not much more difficult. The only pain med that I can take is tramadol but it only takes the edge off the chronic skin pain. My bet is you have a form of MCAD, but I'm not an expert on that form only my own. I think all of us know what you mean by it stealing our lives. I was even in my 60's a very good tennis player & enjoyed participating or going to see the pro's play. I can't do that any more because of the not being able to be in the sun for any length of time. I've lost most of my tennis friends, my coworkers think I'm wierd on my health, as I have no overt signs of health issues in fact quite the opposite. But I have to be thankful many people with masto issues have it a lot worst than me. I feel your resentment as even going on 5 years now I'm still mad about how my life has changed.
Good luck
