Green tea
Green tea is low in histamine and one of the gentler tea options, with minimal processing and moderate caffeine.
Green tea is minimally processed — the leaves aren't oxidized — which means it avoids the biogenic amines that build up in black or oolong teas during production.
-
Low processing, low amines — because the leaves are quickly heated after picking to stop oxidation, green tea doesn't accumulate the same compounds that more processed teas can; this makes it one of the more comfortable tea choices
-
Caffeine is still present — green tea has less caffeine than black tea but it's not caffeine-free; caffeine raises adrenaline, which can produce sensations like flushing or a racing heart that overlap with histamine symptoms
If caffeine sensitivity is a factor, white tea tends to have even less caffeine while keeping the low-oxidation benefits.
