HEMP ALLERGY


Key Allergens

Hemp is a weed of the family Cannabinaceae that produces flowers, leaves and seeds. Hemp seeds are added to cereals, granola and pressed to produce oil.

There are 4 airway allergens associated with hemp allergy.

Can s 2 is a profilin protein, this is a panallergen causing allergies in multiple plants.

Can s 3 is a lipid transfer protein (LTP). This is another common panallergen which has been known to cause serious allergic reactions.

Can s 5 is a pathogenesis related protein, these proteins are also known as Bet v 1 proteins as they affect people already sensitised to birch tree pollen.

Associated Syndromes

A serious allergy to multiple LTP proteins may be a sign of LTP Syndrome.

You may have Pollen Food Allergy Syndrome if you are allergic to multiple tree pollens related to Bet v 1.

Profilins are also found as food allergens in kiwi, celery, peanut, chilli, watermelon, orange, hazelnut, melon, carrot, strawberry, soya, walnut, lychee, lupin, apple, cherry, almond, peach, pear, mustard, tomato and aubergine.
