Are mangoes toxic? #shorts #science #SciShow

The video explains the toxin urushiol, found in Poison Ivy and mangoes, and its role in allergic reactions. If someone is exposed to Poison Ivy first, they are more likely to develop an allergy to mangoes due to the body's recognition of urushiol as a threat. This reaction is specific to the order of exposure because urushiol is present throughout the Ivy plant but mainly in the mango peel, leaves, and stem. Handling a mango first is less likely to trigger an immune response since the stem and leaves are not typically touched.
