Black Seed Oil (Nigella sativa) has a long history of use in traditional medicine systems, particularly in Middle Eastern and South Asian cultures, for promoting overall heart health and treating "heart weakness." Traditional practitioners have used black seed oil to strengthen the heart, improve circulation, and address symptoms related to cardiovascular weakness, though the term "heart weakness" is not clearly defined in modern medical terminology. These uses are rooted in ancient texts and folk remedies, and are often cited in Unani and Ayurvedic medicine.

Scientifically, there is some preliminary evidence suggesting that black seed oil and its key active compound, thymoquinone, may have cardioprotective effects, such as antioxidant, anti-inflammatory, lipid-lowering, and antihypertensive properties. However, most studies to date have been animal-based or involve small human trials focused on surrogate markers like blood pressure, cholesterol, or inflammation, rather than direct evidence for treating "heart weakness" or heart failure in humans. There is not yet robust clinical evidence supporting its use for heart failure or significant cardiac dysfunction.

In summary, while black seed oil is traditionally used for heart support, scientific validation is limited and of low quality. Its use for "heart weakness" is primarily justified by tradition, with modest preliminary scientific interest but insufficient evidence for strong recommendations.
