Welcome to HealthcareMagic forum.
It would have been better if you have mentioned the site of clot formation as well as the reasons for occurrence. Your treating doctor would have known that.
There are no scientific evidences to suggest natural products like garlic would prevent future episodes of clot.
I suggest you to consult your physician and restart ecosprin
. You may also discuss about the events/causes that triggered the clot occurrence in the past and if any other precautions needs to be taken.
Hope this answers your query.
