Bromelain is a natural blood thinner
and anti-inflammatory. It works by breaking down fibrin,
a blood-clotting protein that can impede good circulation
and prevent tissues from draining properly. Bromelain
also blocks the production of compounds that can cause
swelling and pain. When inflammation is reduced, blood
can move more easily to a traumatized area, easing pain
and speeding healing
Quercetin
Quercetin, which is primarily found in apples, onions,
and black tea, is a type of flavonoid (plant pigment)
that serves as a building block for other members of the
flavonoid family. Quercetin appears to help fight a host
of disorders, from asthma to heart disease. As an antioxidant,
it combats the destructive "free radical" molecules
that play a part in many diseases. Quercetin is best taken
in combination with vitamin C; the flavonoid enhances
the vitamin's effect.
