On many websites across the internet, there are articles and videos of unknown origin claiming that various plants (or herbal products) “open up” the arteries. In fact, there is a consensus that many natural plants provide benefits to various tissues in our bodies. This is because we have nourished ourselves with plants found in nature for hundreds of thousands of years, living and evolving to adapt to them. There likely is a plant specifically beneficial to the arteries; however, such a specific effect of any plant has not yet been scientifically
proven. Remember, there is a concept called “placebo”; if you believe it, you feel it. That is to say, a patient who says, “
I used to have chest pains, but my arteries opened up thanks to this plant,” is not actually lying. Indeed, because the brain, believing in the remedy, alters the perception of pain for a while, the patient temporarily stops feeling it. The issue here is the incorrect use of the phrase
“opening the arteries” instead of
“temporary disappearance of chest pain.” To claim that a herbal product opens the arteries, it must be proven. In science, the process required for proof is simply this: For example, you take 2,000 patients with coronary artery disease and divide them into two groups of 1,000 each. You ensure that the groups have similar averages regarding characteristics vital to vascular occlusion, such as age, gender, hypertension, diabetes, and smoking (this is naturally achieved with such a large number of patients). Then, you give one group the herbal product in a specific dose, schedule, and duration, while the other group does not receive it. After, say, 10 years, you perform angiograms on all patients again. You compare the degree of vascular occlusion detected in the angiogram with the angiographic images—i.e., the occlusion levels—from just before the scientific study began. If you demonstrate, through objective and reproducible methods, that the occlusions in the group given the herbal product have improved or at least worsened less than in the other group, then you can say that the herbal product opens arteries or at least might be beneficial. To guard against potential errors in obtaining or evaluating scientific data, other researchers conduct the same study on different patient groups; if they repeatedly reach the same conclusion as yours, you can then be certain of this information. Beyond this, any claim—especially personal anecdotes—holds no significant weight in science (this is somewhat similar to the low reliability of individual testimonies in criminal cases). Therefore, ask someone who claims “
This plant (or herbal product) opens the arteries” the following:
- “Have you performed an angiogram or a similar imaging test that proves whether the vessels opened by comparing them with old images after giving patients this plant/product?”
- “Why do you not publish such a miraculous discovery, which solves the problem of cardiovascular diseases—the number one cause of death in the world—in high-quality scientific journals?”
While it can sometimes have harmful effects such as drug interactions or toxicity, consuming most plants generally does no harm. The real problem is when a person, thinking their arteries will open with a herbal product, abandons their existing medical treatment. When the organ in question is as vital as the heart, the consequences are unfortunately severe. Financial loss is another dimension of the matter. Scientists generally do not support individuals who sell or recommend a specific herbal product for a specific effect due to doubts about their integrity. However, some of these individuals, including those who are doctors, sincerely believe in the specific effects of herbal products. In any case, the key point that allows us to find the truth is this:
Science is based on evidence.
