Further study on herbal shampoos and head lice

A new study further analyses herbal shampoos for their ability to kill head lice.

The study, authored by Soonawera and published online in Parasitology Research in June 2014, tested three herbal shampoos based on native Thai plants compared to commercially available shampoos.

The three herbal shampoos tested (from Acorus calamus Linn., Phyllanthus emblica Linn., and Zanthoxylum limonella Alston) were found to have higher pediculicidal activity than carbaryl or malathion shampoos in both in vitro and in vivo tests.

This result is in line with previously reported results for shampoos from natural products published recently.
