Is curry leaf high in nightshades?

Watch for

Not curry powder, and not related to it. Curry powder blends usually include chilli (a nightshade), sometimes anticaking agents and occasionally a wheat or rice carrier, so logging one as the other will pin a reaction on the wrong ingredient entirely / The tempering pan is where the real triggers are. Curry leaf is fried into hot oil with mustard seed, dried chilli (nightshade), onion and garlic (fructans) and often ghee, and any of those is a more likely culprit than the leaf / Asafoetida is the sleeper in that same pan: commercial hing is usually compounded with wheat flour as a carrier, which makes it a real and frequently missed gluten exposure in South Indian cooking / Fresh and dried behave the same on triggers, but dried leaves lose most of their aroma, so recipes call for more of them. That is a flavour compromise, not a change in trigger load / Whole leaves are normally left in the dish and pushed to the side of the plate rather than eaten, like bay leaf, so actual intake is smaller than the ingredient list implies
