Ainsworths is a homoeopathic pharmacy and manufacturer in London. They sell homoepathic products,  Bach flower products, vitamins, lactose powder, pellets and pills.

In spite of proudly advertising on top of the website that:

Ainsworths homeopathic products are without approved therapeutic indications

they make the most surprising claims about how homoeopathic products can prevent leptospirosis better than vaccines. Huh? There is no such thing as a vaccine against leptospirosis… This story seems to be made out of whole cloth, but I will investigate it further before I make a firm statement.
