Beta blockers are also known as beta-adrenergic blocking agents. They treat many health problems but are most often used in the treatment of heart or circulatory conditions. This class of drugs works to reduce blood pressure by blocking adrenaline to the heart. The medications allow the heart to beat less forcefully and slowly in order to reduce blood pressure. Some herbal substitutes can be used in place of beta blockers; however, all remedies should be approved by a physician.


Garlic has moderate blood-pressure-lowering effects and should be taken regularly for significant effects. Garlic can be taken as a powder, raw, extract, juice, syrup or tincture. To use in place of a beta blocker, follow labeling directions to take a dose that is the equivalent of one-half to two raw garlic cloves daily.


Hawthorn is an effective beta blocker substitute because it can steady the heartbeat, increase the heart’s tolerance to oxygen deficiency during high stress happen or excitement and calm the nervous system. To use hawthorn as a beta blocker substitute, add two teaspoons of crushed leaves or fruit to one cup boiling water and drink twice daily. Hawthorn can also be taken as a supplement in capsule form; the usual dosage is two to three 450-milligram capsules daily.


L-arginine is used as a beta blocker herbal substitute because it changes into nitric oxide, which causes blood vessel relaxation (and lowers blood pressure). To use L-arginine in place of a beta blocker, take two to three grams by mouth three times daily for up to six months.


Passionflower is an herb that is believed to increasing levels of a chemical called gamma-aminobutyric acid which lowers the activity of some brain cells. The result is relaxation and reduced anxiety. Capsules, liquid extracts, teas and tinctures of passionflower can be found in the health food stores. To use as a beta blocker substitute, adults should steep about one teaspoon of dried passionflower in one cup of boiling water for 10 minutes before straining and drinking. This should be used three to four times daily.

The tea should be fragrant and fresh to work properly. Chamomile tea is a popular relaxation remedy and has been used by people all over the world for centuries. One cup daily can keep blood pressure in control.
