Manuka Mouthwash is a natural herbal mouthwash made from New Zealand native Manuka and Tanekaha, which help to kill the odour-causing bacteria that cause bad breath. In vitro tests commissioned by Kiwi herb on preparations containing a combination of Manuka and Tanekaha have found activity against the common oral bacteria Streptococcus mutans, Streptococcus mitis, and Actinomyces naeslundii. Naturally flavoured with Aniseed, Liquorice and Peppermint oil for fresh breath, Kiwi herb Manuka Mouthwash leaves the mouth feeling fresh and clean.
