Thank you for bringing that up @yidneth, i actually forgot to mention that Aloe can be an allergenic too.
Luckily you can still use it for the skin, which i think is where you can see most benefits from the plant anyway - there are a lot of beneficial things that we can eat, bot not a lot of them can be applied topically.
I cannot touch for example the skin of zuchinni my skin peels bit I love to eat them. Aloe have not tried pure, on cosmetics I feel fine, but once I drank juice as recommended by my father and yes, try first. Lol we should with everything anyway.
