I did not interpret the information on androgrphis (AP) as professionally as you. I'm was not aware of blood thinning. I use nattokinase for that function; so I will be careful.
This info is what I thought I understood for the cardiovascular benefit of AP.
"AP inhibited the increase in blood pressure that is caused by noradrenaline. Researchers believe that AP has this antihypertensive effect because it relaxes the smooth muscle in the walls of blood vessels. This relaxation prevents the blood vessel from constricting and limiting blood flow to the heart, brain, and other organs in the body."
Yes, andrographis is also a great sterol source. Sterols relax blood vessels, which lowers blood pressure and helps to increase circulation to the heart preventing arrhythmia. Sterols also bind cholesterol removing it from the body. Preventing blood clots though is also essential for heart disease treatment.
