Thymepearls
A randomized placebo-controlled clinical double-blind study was conducted with four measurement moments: a premeasurement, immediately after the vocal loading, after the subsequent ingestion of the "thymepearl" (TP) in the experimental group and in the control group the placebo, and after a half-hour break.
