“Gist”: Green Tea is added to memory foam formulation
Why it is interesting: Powdered leaves of the Green Tea plant (Camellia sinensis) are added to memory foam formulations in an amount of less than 2% (w/w) on the total composition. The Green Tea is said to kill bacteria, mites and molds and reduce the smell of the foam when used in pillows and mattresses for example. Since tea leaves are also claimed to “brighten eyesight, refresh the brain and resist radiation” it’s hard to know if the claim is true. If it doesn’t work it won’t hurt I guess.

/ September 26, 2016Yes, people have added the strangest things to flex foam formulation. Urine springs to mind, but they won’t usually boast about that :-)
BTW, urine would be a better choice than Cola I guess.. Cola is very acidic while urine has some pre-made urea in it :-)
