I think there's two or even three shops in SA. Natures cradle (Nature's Cradle, 425 Brighton Road,
Brighton, AND Nature's Cradle, Shop 5/69 Gawler St, Mt Barker,) and...hm, someone else will have to answer for the others!

Also - bamboo and hemp both have anti-bacterial and anti-fungal properties so are actually good to have against a red bott.
