Overview
About Calabash
Calabash, the pale green bottle gourd sold as lauki, dudhi or opo squash, is graded clean across every trigger this journal tracks.
No histamine, no salicylate, no oxalate load, no nightshade, no gluten or lactose, no nickel, no lectin flag, and it fits AIP, DASH and Mediterranean patterns. Its FODMAP content is unrated rather than tested, which is the only gap. So the reason this page exists is not intolerance, it is a real acute hazard that a food journal will never catch: bottle gourd sometimes accumulates cucurbitacins, the intensely bitter defence compounds of the gourd family, and a bitter bottle gourd is poisonous. Indian hospitals have documented vomiting, gastrointestinal bleeding and deaths after people drank raw lauki juice as a health drink. The rule that came out of that is simple and worth following every single time: taste a small raw piece first, and if it is bitter, spit it out and throw the whole gourd away.

How Calabash scores
Watch for
What trips people up
- Taste before you cook or juice, every gourd, every time. Bitterness is the only warning sign cucurbitacin gives you. If the raw sliver tastes bitter, discard the entire fruit rather than trying to cook the bitterness out, because cucurbitacins are not reliably destroyed by heat
- Raw juice is the dangerous form. An ICMR expert committee was convened in India specifically because of bottle gourd juice poisonings, and reported cases indicate that around 50 mL of bitter juice can produce serious illness while larger volumes have proved fatal. There is no antidote and treatment is supportive only
- If you have swallowed bitter bottle gourd and then get vomiting, diarrhoea, abdominal pain, blood in vomit or stool, or simply feel very unwell, treat it as an emergency and get medical help rather than waiting it out
- On the intolerance side there is genuinely nothing to report. Calabash grades clean on histamine, histamine liberation, salicylate, oxalate, lectin, nickel, sulfite and glutamate, and it is AIP compliant. Its FODMAP grade is unrated rather than proven low, so log your portion if you have IBS and are still mapping thresholds

FAQ
Common questions about Calabash
Is bottle gourd juice safe to drink?
Only if the gourd is not bitter, and you have to check rather than assume. Raw lauki juice became popular in India as a wellness drink and produced a run of serious poisonings, including deaths, which is why an ICMR expert committee looked at it. The committee advice is that bitter tasting bottle gourd juice must not be consumed, and that anyone who develops nausea, vomiting, diarrhoea or any feeling of unwellness after drinking it should be taken to hospital straight away. Taste a raw piece of the gourd before it goes anywhere near a juicer.
Why does my lauki taste bitter?
Cucurbitacins. They are the bitter tetracyclic triterpenoids that wild gourds evolved as a defence, and cultivated bottle gourd can revert to producing them, usually after heat or drought stress, irregular watering, or cross pollination with a wild or ornamental gourd. You cannot see it, smell it or predict it from the plant, and one gourd on a vine can be bitter while its neighbour is fine. Bitterness is the whole test.
Does cooking make a bitter bottle gourd safe?
No. Cucurbitacins are stable enough that cooking is not a dependable way to remove them, and masking the taste with spice only removes your warning signal. The taste test applies to the gourd you are about to put in a curry just as much as the one you are about to juice. If in doubt, throw it out. Bottle gourd is cheap and the downside is not.
Is calabash low FODMAP and AIP friendly?
It is graded AIP compliant and clean on fructans, GOS, excess fructose and polyols, so the individual FODMAP groups look good. The overall FODMAP grade is unrated rather than confirmed low, meaning no tested portion size exists for it. In practice that makes it a reasonable vegetable to trial early on a restricted diet, logged with a portion size, rather than one to treat as a proven free food.
