As part of a natural treatment for blood pressure issues, you should of course first inform your treating physician. Then, everything will depend on the person, their age, and their treatment, in order to avoid any interaction.

In addition, black seed also has benefits for arterial health. A small teaspoon of the oil in the morning and one in the evening, alone or with honey, will be beneficial.
There is also a Chinese mushroom known for lowering blood pressure: shiitake.
Finally, there is a little-known fruit called "noni," which is very beneficial for blood pressure. It can be found in syrup form.
