CURRY LEAF ALLERGY
Curry leaf is harvested from the curry tree which is in the Rutaceae
family of plants. Other plants in this family are citrus fruits including grapefruit, lemons, limes and oranges. The leaf is used for its flavour and smell, which makes it very popular in Indian and other South Asian cuisines. Other citrus fruits can be eaten, but the ones from the curry plant are an acquired taste. The seed of the curry plant is toxic to humans and should not be eaten.
Curry leaf should not be confused with curry powder which is a blend of other aromatic herbs and spices. The FOOD ALLERGY INDEX
contains most of the spices included in curry mixes.
Curry leaf contains lots of fragrance compounds including cinnamaldehyde and cinnamal which can cause contact allergic dermatitis. It is especially linked to occupational contact dermatitis, with those who pick the leaves or cook a lot with them.
Curry leaf is a low FODMAP food in normal portions. FODMAP stands for F
olyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.
You can read more about Food Intolerances
