Arjuna and heart palpitations: what to know

Arjuna usually refers to an herbal product made from Terminalia arjuna. Do not use it to diagnose or treat an abnormal heartbeat on your own, and tell a clinician exactly which product and dose you took.

Palpitations may feel like pounding, fluttering, skipped beats or a racing pulse. They can occur with stress, caffeine, dehydration, thyroid problems, anaemia or a heart-rhythm disorder. Atrial fibrillation can present with palpitations, but the sensation alone cannot identify the rhythm.

A supplement can contain several active substances, and products may differ in strength or added ingredients. The timing of symptoms in relation to each dose matters, but timing by itself does not prove that arjuna caused them.

Pause the arjuna product until a clinician or pharmacist has reviewed it, especially if the palpitations began after starting it or changing the dose. Do not stop prescribed heart, blood-pressure or blood-thinning medicine unless the prescriber tells you to.

Write down when episodes start, how long they last, whether the pulse feels regular, and any dizziness, breathlessness or chest discomfort. Bring the container or a clear ingredient photo and list all medicines, supplements, caffeine products and decongestants you use.

Call emergency services for palpitations with chest pain, fainting, severe breathlessness, new confusion, marked weakness or symptoms that feel immediately dangerous. Do not drive yourself if you feel faint.

Arrange prompt clinical review when episodes recur, last longer than usual, occur during exercise, or accompany a known heart condition. An examination and an electrical recording of the heart may help identify the rhythm.

Ask whether any ingredient could interact with your medicines, whether your pulse should be recorded during an episode, and whether blood tests for anaemia, thyroid function or body salts are appropriate. Also clarify whether it is safe to restart the product.
