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.
