Role of Blood Thinners

Blood thinners are valuable healthcare medications. Also known as anticoagulants, they play a big role in avoiding or decreasing the formation of blood clots. They also help manage conditions like deep vein thrombosis along with strokes. This is done by ensuring smoother blood flow through the arteries and veins without the risks of clotting.

Blood thinners come in handy for a range of conditions:

  • For specific heart conditions
  • Post-surgery of heart valve replacement
  • Abnormal heart rhythms
  • To reduce post-op blood clot problems

What is the effect of marijuana on the body?

Medical cannabis or medical marijuana is a cannabis plant. The compounds in the plant treat various health conditions. It contains two primary compounds, THC and CBD.
