I am still using my batch from the fall 2009. Had a nasty feeling in my guts last night -something I ate? and a dose of tonic set me right again. And it is the best thing I've got for warding off colds/sore throats.
Love this stuff. I'm down to three jars - I want to grow some of the ingredients this summer and make a new batch in the fall so I don't risk running out.
