Rosemary essential oil is extracted from the leaves of the rosemary plant by steam distillation. It contains a variety of bioactive components, including cineole, camphor, and rosmarinic acid, which help to enhance its medicinal qualities. Rosemary essential oil is colorless with an aromatic fragrance used in skin and hair care. It is used in various cosmetics and skincare products for its skin benefits. It positively impacts the brain cells to give a charismatic and positive mood. However, it also raises the blood pressure slightly. Even though rosemary oil is good for reducing blood pressure levels and heart rate levels due to its diuretic property that removes fluids from the body and may lead to dehydration due to the elimination of salt and water from the body to vary blood pressure level.

Moreover, the oils are good for the body but if taken or used in large quantities then might be cautious as it may lead to mood swings and sleeplessness. It is seen that the more the fluid is more pressure on the blood vessels and the more the blood pressure, rosemary essential oil temporarily raises the blood pressure leading to a high flow of blood in the body to normalize the body temperature and eventually it also reduces the blood pressure in the body that makes a person feel good.

Some say that rosemary essential oil does not reliably raise blood pressure. While some studies have found that inhaling rosemary oil vapor may temporarily elevate blood pressure and heart rate, these effects are usually moderate and brief.

There is evidence that rosemary essential oil may assist in decreasing blood pressure in some cases. Its diuretic characteristics stimulate fluid removal from the body, which can reduce blood volume and hence lower blood pressure. Furthermore, rosemary oil has been demonstrated to have vasodilatory properties, which means it can relax blood vessels and enhance blood flow, adding to its possible antihypertensive effects.

Moderation is key with any essential oil or herbal remedy; understanding the science behind rosemary essential oil and its effects on the body enables informed decisions, fostering safe and responsible enjoyment of its benefits.
