I am a big fan of this, especially during the winter months for immune system support.
It is potentially anti-viral (the active ingredient / polyphenol is Oleuoropein), and the concentration is much more potent in liquid form over cheaper capsules.
Cheapest price on 3 camels (Amazon) is approx £14 delivered in past year.....I have only ever had it at £10 a bottle direct from comvita when it was very near expiry (this batch is 09/17, no problem!)
Mine arrived from Bodykind in 3 days, free p&p, excellent service.
Hope this helps someone :)
