From the Guidelines
There is no established dosing regimen for rosemary specifically for dementia treatment, and it should not be used as a primary treatment for dementia. While some preliminary research suggests rosemary may have cognitive benefits through its antioxidant properties and ability to inhibit acetylcholinesterase (similar to some dementia medications) 1, it is not approved or recommended as a primary treatment for dementia. For those interested in trying rosemary as a complementary approach, common forms include rosemary essential oil for aromatherapy (a few drops in a diffuser), rosemary tea (1-2 teaspoons of dried rosemary steeped in hot water for 5-10 minutes), or rosemary extract supplements (typically 750-1500mg daily, divided into doses) 1. These should only be used as complementary approaches alongside conventional medical treatment prescribed by a healthcare provider. Rosemary may interact with certain medications including blood thinners, diuretics, and medications for high blood pressure or diabetes, so consultation with a healthcare provider is essential before starting any rosemary regimen, especially for someone with dementia who may be taking multiple medications 1. The most recent and highest quality study on dementia treatment emphasizes the importance of conventional medical treatment and the need for further research on complementary approaches like rosemary 1. Key considerations for dementia treatment include:
- Conventional medical treatment should be the primary approach
- Complementary approaches like rosemary should be used with caution and under healthcare provider guidance
- Potential interactions between rosemary and other medications should be carefully considered
- Further research is needed to fully understand the effects of rosemary on dementia symptoms and treatment outcomes 1.
From the Research
Rosemary Dosing for Dementia
- There is limited research on the specific dosing of rosemary for dementia, but some studies have investigated the effects of rosemary and its components on cognitive function.
- A study published in 2012 2 found that a low dose of dried rosemary leaf powder (750 mg) had a statistically significant beneficial effect on speed of memory in older adults, while a higher dose (6,000 mg) had a significant impairing effect.
- Another study published in 2020 3 used a Melissa officinalis extract containing rosmarinic acid, a component of rosemary, and found that a daily dose of 500 mg was safe and well-tolerated in patients with mild dementia due to Alzheimer's disease, and may help prevent the worsening of AD-related neuropsychiatric symptoms.
- However, it is essential to note that these studies had different designs, populations, and outcomes, and more research is needed to determine the optimal dosing and efficacy of rosemary for dementia.
- Other studies have investigated the effects of various drugs and supplements on cognitive function and dementia, including acetylcholinesterase inhibitors, memantine, and Ginkgo biloba 4, 5, 6, but these are not directly related to rosemary dosing.
