A young Arizona mother of twins has been left critically ill in hospital after suffering a heart attack, reportedly linked to a kratom supplement her husband suggested she try for leg pain. The product, described as having been bought from a petrol station, is part of a herbal supplement category that has faced growing scrutiny over safety concerns and inconsistent regulation in the United States.

Kratom, derived from a Southeast Asian tree, is often sold over the counter as a pain relief or energy aid but is not approved by the US Food and Drug Administration and has been linked in past cases to serious cardiac and other health complications. Full details of the woman's current condition, her age, and the specific product involved were not included in the available article text.
