Where it comes from
The tree keeps growing after you take the sap.
Latex is tapped from Hevea brasiliensis through a shallow downward cut in the bark that opens the vessel network without harming the tree. The cut heals, the tree carries on, and the same trunk can be tapped for decades, which makes a living rubber tree worth more standing than felled.
The finished latex is tested to OEKO-TEX Standard 100 Class 1, which is the strictest tier there is, the one written for products intended for infants. It screens more than a hundred harmful compounds including PFAS, formaldehyde, heavy metals, pesticide residue and phthalates.
