I highly recommend this alternative, natural remedy for asthma and COPD patients. In my honest opinion, it works better than my emergency inhaler or my nebulizers. Half a dropper full of this extract works wonders for your breathing ability; and it's a whole lot better than chemical drugs with their side effects. 5 1 ounce bottles will last me over 6 months; taken once daily. Only $15.66 for 5 bottles on Amazon Prime. You can also find it on the Walmart website, but not at this price.
