Introduction
In general, fennel does not have the effect of lowering blood pressure. Fennel cannot replace antihypertensive medications in controlling blood pressure. Using it as a method to lower blood pressure may delay proper blood pressure management. Controlling blood pressure should follow professional guidance, employing scientifically-based lifestyle modifications and necessary pharmacological treatments.
Generally speaking, fennel usually does not have the effect of lowering blood pressure. The detailed explanation is as follows:
Fennel contains volatile oils, vitamins, and other substances; however, currently, there is no clear evidence indicating these components can directly act on the vascular system or blood pressure regulation mechanisms to effectively lower blood pressure. Its auxiliary promotion of blood circulation mainly occurs through mild regulation of qi and blood movement. This effect is relatively mild and not a specific regulation targeting blood pressure, thus unable to reduce actual blood pressure readings. Additionally, as a common food ingredient, the quantity of fennel consumed is limited, making it difficult to achieve any significant effect on blood pressure through normal dietary intake.
Fennel cannot replace antihypertensive medications in controlling blood pressure. Using it as a method to lower blood pressure might delay proper blood pressure management. Blood pressure control should follow professional guidance, employing scientifically-based lifestyle modifications and necessary pharmacological treatments. Patients with hypertension should avoid relying on ingredients like fennel to regulate their blood pressure and instead regularly monitor their blood pressure and follow medical advice for timely interventions to prevent health risks caused by blood pressure fluctuations.
