Ouch! I check every fruit drink and mixed fruit before I buy it to make sure it doesn’t contain mangoes. I have always been highly allergic to poison ivy but never knew about mango. Many years ago, before they were common in grocery stores, I ate a fresh mango and my whole face and mouth broke out. The Dr. thought I had some unknown disease. It was b-a-d. Never again.
“Mango peel contains urushiol, the chemical in poison ivy and poison sumac that can cause urushiol-induced contact dermatitis in susceptible people.[28] Cross-reactions between mango contact allergens and urushiol have been observed.[29] Those with a history of poison ivy or poison oak may be most at risk for an allergic reaction to mango skin.[30] This compound is also present in mango leaves and vines. During mango’s primary season, it is the most common source of plant dermatitis in Hawaii.”
