Latex
Some people only experience a mild allergy when exposed to latex, like eczema, contact dermatitis or developing a rash. 

Others have a serious latex allergy, and exposure to latex products such as latex gloves can cause anaphylactic shock. Guayule latex has only 2% of the levels of protein found in "Hevea" latexes, and is being researched as a lower-allergen substitute. Additionally, chemical processes may be employed to reduce the amount of antigenic protein in "Hevea" latex, yielding alternative materials such as Vytex Natural Rubber Latex which provide significantly reduced exposure to latex allergens.

About half of people with spina bifida are also allergic to natural latex rubber, as well as people who have had multiple surgeries, and people who have had prolonged exposure to natural latex.
is aloe vera a fruit or a vegetable UNANSWERABLE how would you describe "aloe vera"? Aloe vera" is a stemless or very short-stemmed plant growing to 60–100 cm (24–39 in) tall, spreading by offsets.

It  is intolerant of heavy frost and snow,resistant to most insect pests. In pots, the species requires well-drained, sandy potting soil and bright, sunny conditions. "Aloe" plants can burn under too much sun or shrivel when the pot does not drain water. where is this plant used? Two substances from "Aloe vera" – a clear gel and its yellow latex – are used to manufacture commercial products. how was it used as a medicine traditionally? As a skin treatment can you explain the yellow substance you mentioned above? Latex is a stable dispersion (emulsion) of polymer microparticles in water. how is it used in the making of clothes? Worn on the body (or applied directly by painting), it tends to be skin-tight, producing a "second skin" effect.
