2. Green Leafy Vegetables
There are certain drugs that make your blood thin like as Coumadin® (warfarin), it interferes with Vitamin K-dependent clotting factors. Intake of too much green leafy vegetables can decrease the ability of blood thinners to prevent clotting, as almost every green leafy vegetables are high in vitamin K but that does not mean that you should stop eating all the green leafy vegetables.
The problem is not those vegetables, in fact, the problem is the high intake of those vegetables as it can affect the body in a negative way as it alters the characteristics of the medicine. So we should eat the vegetables but in a consistent manner.
3. Natural Black Licorice (Glycyrrhiza)
According to Plogsted, glycyrrhiza — a natural ingredient used to make black licorice, it can reduce the potassium of the body and can increase the sodium of the body. When your body is depleted of potassium, the activity of digoxin, a medication which is used to treat heart failure, can be greatly higher, which can affect the heart beat rate as well.
Glycyrrhiza can also decrease the effectiveness of high blood pressure medicines. So people who used to take Coumadin® (warfarin) should be well aware of the negative effects of the Glycyrrhiza, as it can break down the drug and results in an increase in the body’s clotting mechanism. So one should avoid the excess amount of natural licorice when taking such medications.
