Does Ashwagandha Help Reduce Heart Palpitations?


Most palpitations are caused by heart-related problems or anxiety and stress. Ashwagandha protects the heart by reducing the bad cholesterol levels and can also lower the systolic blood pressure when combined with arjuna. An overactive T3 hormone, especially in hyperthyroidism patients, and high cortisol levels cause palpitations too. Ashwagandha can regulate T3 and lower cortisol levels by 28%, thus reducing palpitations.

Do you notice your heartbeat kicking up or a fluttering sensation in your chest when you are anxious, nervous, or stressed? Or even all of a sudden? Don’t brush these observations aside as inconsequential. A research finding published in the American Journal of Medicine stated that among the study subjects, 43 percent had palpitations because of heart-related diseases and 31 percent because of psychiatric diseases.1

Why You Should Take Palpitations Seriously

Though palpitations do not necessarily imply any serious underlying medical condition, they do need to be taken seriously if arrhythmia or irregular heartbeat is noticed.2

Some common causes for heart palpitation are:

  • Anxiety, stress, panic attack, or fear
  • Caffeine or nicotine intake
  • Drug abuse
  • Diet pills
  • Exercise
  • Fever

Probable underlying problems include3:

  • Heart disease
  • Abnormal heart valve, such as mitral valve prolapse in which the two flaps of the mitral valve do not close evenly and bulge upward into the left atrium
  • Abnormal level of potassium in blood
  • Reaction to medicines including those used to treat asthma, high blood pressure, or heart problems
  • Overactive thyroid gland
  • Low level of oxygen in blood

Ashwagandha is a herbal remedy that is useful in reducing palpitations. Let’s see how it helps.

How Ashwagandha Treats Palpitation

Reduces Cortisol Levels

The stress hormone, cortisol, gets released into the blood stream at times of stress. People undergoing stress typically experience irregular heartbeat and palpitations. Ashwagandha is known as an adaptogenic herb, or a herb that’s effective in managing stress.

A study on stressed people showed that administering high-concentration, full-spectrum ashwagandha root extract in the form of capsules for 60 days brought the cortisol levels of the test subjects down by 28 percent.4 The decrease in cortisol levels also marks a reduction in palpitation.

Manages Anxiety

Palpitations are a common symptom of anxiety, whether it is chronic anxiety or caused by an immediate factor. A study done at the Department of Pharmacology, University of Texas Health Science Center, indicated that ashwagandha extracts acted like GABA, the neurotransmitter that regulates anxiety. This is the reason ashwagandha is touted as an anti-anxiety herb.5

Regulates Thyroid Activity

When the thyroid gland acts more than it should, it produces more thyroid hormones than the body needs. This extra hormone speeds up the body’s metabolism, making it work harder than it needs to and in the process making one experience nervousness, anxiety, excessive sweating, and palpitations.

Ashwagandha can help by stimulating the thyroid to selectively increase the T4 hormone levels and reducing oxidative stress or making the body able to cope with the increased oxidation. It can also slow down and regulate the production of active T3 hormone, which is what causes the problems associated with hyperthyroidism. This also lowers the anxiety and brings the heart rate back to normal.

Lowers The Systolic Blood Pressure

In one study, a combination of the aqueous root extract of ashwagandha and aqueous bark extract of arjuna were seen to bring down the systolic blood pressure by 4.37 percent. The systolic pressure refers to the force that blood exerts on the artery walls when the heart contracts to pump out the blood.6

Protects Against Heart Diseases

Some palpitations are symptoms of arrhythmia, which could be an indicator of underlying heart conditions including heart attack, heart failure, and heart valve problems. Ashwagandha helps improve heart health by reducing cholesterol and triglyceride levels.

In one study, researchers selected as study subjects patients who had heart attacks caused by the lack of blood supply, patients with low blood supply, a condition known asmyocardial ischemia, and patients with reperfusion injury, which is actually tissue damage caused by the restoration of blood supply after a period of low blood supply or oxygen supply.

When they were treated with ashwagandha, it was found that the herb increased the heart rate, its capacity to contract and relax, and its ability to inhibit the oxidation of lipids in the cell membranes, a process known as lipid peroxidation, that results in cell damage.7 8

Another study on patients with high cholesterol found that administering ashwagandha for 30 days decreased their blood glucose, serum cholesterol, triglycerides, and LDL (bad cholesterol) levels.9

Therefore, it is safe to believe that ashwagandha helps maintain proper functioning of the heart, which in turn leads to a decrease in the factors contributing to palpitations.10

Restores Electrolyte Balance

Potassium, a common electrolyte in the body, plays an important role in controlling the electrical balance of our heart. Low levels of potassium can lead to irregular heartbeat or other electrical malfunction of the heart.

In a study conducted on rats with gentamicin-induced kidney toxicity, it was confirmed that ashwagandha plays a role in restoring electrolyte levels to normal.11

Gentamicin, an antibiotic, disturbs the balance of electrolytes like serum potassium, sodium, magnesium, and calcium. The roots of ashwagandha, however, contain two active ingredients that contribute to the herb’s biological actions—withaferin A and withanolides—which increase the potassium levels in the body and can help reduce heart palpitations.

Given that ashwagandha reduces cortisol levels and brings down the blood pressure by lowering cholesterol levels, it is one of the best herbs for people with palpitation due to either stress or blood pressure issues. Besides taking 1–2 teaspoons of ashwagandha root or leaf powder twice daily boiled in water or mixed with milk or honey, avoid stimulants like alcohol, tobacco, and caffeine, and even diet pills.

But if your palpitation is accompanied by shortness of breath, severe chest pain, unusual sweating, and dizziness, consult your GP immediately.
