Manuka Honey is extremely stable, not affected by light, heat nor dilution. Australian by Nature New Zealand Manuka Honey is 100% natural with no additives. Bio-active Manuka Honey can be used both orally and topically, providing amazing healing properties and nutritional benefits when consumed.Each batch of Manuka Honey 12+ is tested and certified by an accredited laboratory under the ISO17025 standard for its MGO (Methylglyoxal).
