“You may know rosemary as a culinary herb but not as an herbal medicine. Its chemistry is actually quite complex and includes many phenolic compounds (a class of antioxidant chemicals found in grapes, pomegranates, and green tea) with powerful protective actions. Adding it to your diet on a regular basis, even supplementing daily, will let you reap the well-known anti-aging and protective effects of the antioxidants it contains.
Rosemary has been known throughout history to invigorate the nervous system and brain function, reduce fatigue, help alleviate headaches, strengthen digestive function, and benefit the cardiovascular system. In particular, its connection to the health of the heart and cardiovascular system is ancient. That makes sense, considering rosemary’s powerful antioxidant and protective properties, along with the beneficial effects it has on circulation.
Rosemary has a long reputation for helping to regulate menstrual flow and ease cramping pain. In traditional Chinese medicine, pain anywhere in the body is thought to result from the stagnation of blood and vital energy, so it follows that rosemary relieves pain as it invigorates the circulation of energy and blood throughout the body.
Rosemary is a common ingredient in hair preparations, perhaps because of its invigorating and stimulating effects on the circulation of the hair follicle.
Shakespeare wrote, “Rosemary, that’s for remembrance,” a saying that every herbalist knows. It refers to this herb’s long-standing tradition as a beneficial memory herb.
Rosemary has a taste of AROMATIC and a temperature of WARM.”
Rosemary has a long history in traditional medicine, dating back to ancient Greece and Rome. It was used for improving memory, relieving headaches, and aiding digestion. The herb was also associated with strengthening the heart and as a symbol of remembrance and fidelity.
Modern Clinical Uses by Herbalists and Naturopaths:
- Cognitive Function: Often used to support memory and concentration, believed to enhance brain function.
- Digestive Health: Aids in treating indigestion, bloating, and gas.
- Antioxidant and Anti-inflammatory: Used to reduce inflammation and fight oxidative stress.
- Circulatory Health: Enhances circulation and is sometimes used for improving blood flow and lowering blood pressure.
Chemistry and Pharmacology:
Rosemary contains several active compounds, including:
- Carnosic acid and carnosol, which are potent antioxidants and anti-inflammatory agents.
- Rosmarinic acid, known for its anti-inflammatory, antimicrobial, and antioxidant properties.
- Essential oils, which contain camphor, 1,8-cineole, and α-pinene, contribute to rosemary’s medicinal qualities, particularly its ability to stimulate circulation and alleviate pain.
Clinical Trials
- Cognitive Function: Several studies show rosemary’s positive effects on memory and cognitive function. A study in 2016 demonstrated improved memory performance in individuals exposed to the scent of rosemary.
- Anti-inflammatory and Antioxidant Effects: Clinical trials have highlighted its ability to reduce inflammation and oxidative stress, with some evidence showing its benefits in conditions like arthritis.
- Anticancer Potential: There is ongoing research into rosemary’s potential anticancer properties due to its antioxidant activity, though results are still preliminary.
- Digestive Health: Rosemary has been shown to help with digestive issues, with some studies supporting its use in reducing bloating and aiding digestion.
- In conclusion, rosemary is a versatile herb with a variety of traditional and modern uses, especially in cognitive, digestive, and inflammatory health. Clinical trials support many of its traditional uses, though more research is needed to establish definitive therapeutic guidelines.
