Items containing latex are primarily manufactured from the milky liquid derived from the rubber tree, also known as latex. This natural latex is a sap harvested from the Hevea brasiliensis tree, which is cultivated primarily in tropical regions. The composition of this sap includes various proteins and is responsible for the elasticity and stretchiness associated with latex products.

Latex is widely used in a variety of medical supplies, such as gloves, catheters, and balloons, due to its unique properties, including durability and excellent barrier protection. Understanding the source of latex is crucial, especially in medical settings where patient allergies to latex can pose significant health risks. This recognition informs proper material selection and aids in preventing allergic reactions among patients who may be sensitive to latex proteins.

In contrast, other materials listed in the options, such as polyethylene, silicone, and polyvinyl chloride, are synthetic and do not originate from the rubber tree, which is why they are not considered sources of natural latex.
