Why do the Pukka ‘Wholistic’ remedies contain silicon dioxide as an anti-caking agent?

Silicon dioxide is a natural flowing agent occurring in plant matter known as silica. It is added at a small percentage to Pukka ‘Wholistic’ remedies because they are naturally a little ‘sticky’ from the high levels of essential oils. The silicon dioxide helps all the ingredients blend together easily and it means we don’t have to use synthetic binders like magnesium stearate.
