Grape Seed Extract
Healthline reports 16 benefits of grapes including heart health. The seed extract is obtained from the crushed seeds of the plant. And it’s available as liquid, capsule and tablets as supplements for blood issues.
A 2019 study points to its promising multiple blood thinning properties. But it’s thought to be incompatible with other anticoagulants. Plus little is known about its safety in pregnant and lactating mothers. [19] [20]
Feverfew
From time immemorial, feverfew has been used in traditional medicine to treat and prevent migraine, headache, and fever. Sketchy reports suggest it contracts the uterine during labor.
A 2021 case report predicts a relationship between feverfew and vaginal bleeding. This followed a case of a 36-year-old woman who suffered prolonged vaginal bleeding upon taking 800mg of feverfew thrice per day for 9 months. This probable relationship is linked to the inhibition of thrombin.
While the details of its actions and effects remain sketchy, it should be used with caution with other blood-thinning drugs. [21] [22] [23]
