Black seed (Nigella sativa), also known as black cumin, has a long history of use in traditional herbal medicine, particularly in Middle Eastern, North African, and South Asian cultures. In these traditions, black seed has been used as a general tonic and to support various aspects of health, including heart function and vitality. Historical texts and folk medicine often reference its use for "strengthening the heart" or alleviating "heart weakness," though these terms are not clearly defined in modern medical language.

Scientific studies on black seed's effects on heart health are limited and mostly preclinical. Some animal and small human studies suggest that black seed and its active compound, thymoquinone, may have beneficial effects on cholesterol levels, blood pressure, and oxidative stress, all of which are relevant to cardiovascular health. However, there is insufficient clinical evidence specifically supporting its use to treat or directly improve "heart weakness" (which might refer to heart failure or low cardiac output in modern terms). Thus, while black seed is traditionally used for supporting the heart, robust scientific validation for treating heart weakness is lacking, and its efficacy for this specific indication remains unconfirmed.
