Final answer:
Garlic should not be taken before surgery due to its anticoagulant effects that increase the risk of bleeding.
Step-by-step explanation:
Among the herbs listed, garlic should not be taken prior to surgery due to the risk of increased bleeding. Garlic has natural anticoagulant properties, meaning it can prevent blood clots from forming efficiently. This effect is similar to that of aspirin, which is known to interfere with the action of platelets, leading to an increased risk of bleeding. Individuals scheduled for surgery are often advised to avoid garlic, as well as other supplements with blood-thinning effects, to reduce the risk of excessive bleeding during and after the operation.
The inhibition of endogenous prostaglandin biosynthesis, which plays a role in platelet function and blood clotting, is one mechanism by which garlic and aspirin-like drugs can extend bleeding time.
