If you have a history of allergy, you should not contact with previous sensitizers or allergens. Milk tea has milk and tea as well as ingredients, lactose intolerant people in our country are in the majority, and peanut allergy is also in the minority, so if you are allergic to the ingredients of milk tea, you should not drink it.
