medicine

Recently while cleaning my shelf came across the triphala churnam tablets which have expired by 1 year . Still some 50 tablets are there , should i use it or throw it. Observed that its in good state color or consistency not changed - airtight. Let me know what you guys think - about this .

I have to purchase some medicines for a period of time (unsure but ordering at least for a month). Can you suggest if purchasing medicines online is proper or not.. I cannot list sites details who sell those online, there are many... But fact being online medical shops are offering upto 30%...
