Data was collected using a specially designed questionnaire. Results: Overall frequency of herbal use was 14.1%. The most commonly used herbs in Jordan were hawthorn and ginger. A total of 27 local and one Chinese herbal product were used, while the use of adulterated formulae were absent. Pharmacists were never consulted regarding the quantity or frequency of herb use. Side effects were rare. Conclusion: The use of medicinal herbs among cardiac patients in Jordan is not uncommon and consists largely of local herbs. Active role of pharmacists and doctors for counseling patients on the appropriate use of herbal products should prevent toxicity, ensure proper modes of preparation and optimize safety and efficacy.
