Hi Madelaine
I've used Septoguard before for my little one - our homeopath prescribed it. I'm going to sound really vague now, but here goes - he explained to me that it is similar to viral choice and viral guard and it is used to reduce the occurence of infections, but that it is the only one that can fight bacterial AND viral infections. I THINK that's what he said!! I thought it tasted vile (like cloves), but my LG was quite happy to drink it diluted in water in her bottle. She did get better, so I'm assuming it helped. My homeopath is PASSIONATE about it!
Hope this helps!
