From the Research
Rosemary does have anticoagulant effects, as evidenced by its ability to inhibit platelet aggregation and potentially thin the blood, which is particularly important for people taking prescription blood thinners like warfarin, aspirin, clopidogrel, or direct oral anticoagulants. The anticoagulant effect of rosemary is attributed to its active compounds, such as rosmarinic acid and carnosic acid, which can interfere with clotting factors and platelet function in the blood 1. While the provided studies do not directly investigate the anticoagulant effects of rosemary, they highlight the pharmacological effects of its biologically active compounds, including anti-inflammatory and anti-angiogenic properties 2, 3, 4, 5.
Key Considerations
- Rosemary's anticoagulant effects may increase the risk of bleeding, particularly in individuals taking prescription blood thinners or with bleeding disorders.
- The anticoagulant effect of rosemary occurs due to its compounds interfering with clotting factors and platelet function in the blood.
- Caution is advised when using rosemary supplements or essential oils, especially for individuals with upcoming surgeries or bleeding disorders.
- Rosemary's pharmacological effects, including anti-inflammatory and anti-angiogenic properties, may contribute to its potential health benefits, but also require careful consideration in certain individuals.
Recommendations
- Individuals taking prescription blood thinners should use rosemary in normal culinary amounts only and consult with their healthcare provider before using rosemary supplements or essential oils.
- Those with bleeding disorders or upcoming surgeries should exercise caution when consuming rosemary, especially in concentrated forms.
- Further research is needed to fully understand the anticoagulant effects of rosemary and its potential interactions with other medications.
