Every part of every fruit and vegetable has a purpose. Pineapple is something I strongly recommend for hypertension and is an amazing blood thinner that actually thins blood due to the powerful enzyme bromelain.
Next time you eat a pineapple, do not throw away the skin. Get a pot of water, add the pineapple skin, bring to boil then simmer for 20 minutes, cool then strain, now add some honey, pour some pineapple skin tea, stir and enjoy. Put any remaining tea into an airtight container and store in fridge. Warm up each time you wish to drink.
Pineapple skin tea is packed with vitamin c, maganese, boosts immunity, strengthens teeth, boosts digestion, increases red blood cells, beautifies skin, reduces inflammation plus so much more due to the powerful enzyme bromelain released in water. This liquid is gold.
