5 Herbs That May Help Slow or Prevent Alzheimer’s—Backed by Science

Herbs have long been recognized for their potential health benefits, and some may even play a role in slowing or preventing Alzheimer’s disease. Here are five herbs that have shown promise in scientific studies:

1. **Rosemary and Sage**: These herbs contain a compound called carnosic acid, which is known for its antioxidant and anti-inflammatory properties. Researchers have synthesized a stable form of carnosic acid called diAcCA, which has shown promising results in mouse models of Alzheimer’s disease. It not only improved memory but also increased the density of synapses in the brain, which are crucial for cognitive function[1].

2. **Thyme**: Thyme is another herb rich in antioxidants and has been part of traditional Mediterranean diets, which are associated with better cognitive health. While specific studies on thyme and Alzheimer’s are limited, its antioxidant properties could contribute to reducing oxidative stress, a factor in neurodegenerative diseases[2].

3. **Basil**: Like thyme, basil is a staple in Mediterranean cuisine and is rich in antioxidants. While direct research linking basil to Alzheimer’s prevention is scarce, its antioxidant properties could help mitigate oxidative stress, which is linked to neurodegeneration[2].

4. **Oregano**: Oregano is known for its strong antioxidant properties, which can help protect against oxidative stress and inflammation. These properties are beneficial in reducing the risk factors associated with Alzheimer’s disease, although specific studies on oregano and Alzheimer’s are limited[2].

5. **Lavender**: While lavender is more commonly associated with its calming effects, some studies suggest that it may have neuroprotective properties. However, direct evidence linking lavender to Alzheimer’s prevention is still emerging, and more research is needed to confirm its potential benefits[2].

Incorporating these herbs into your diet, especially as part of a Mediterranean-style diet, may offer additional health benefits. However, it’s important to consult with healthcare professionals before using any herbal remedies, especially if you are considering them as part of a treatment plan for Alzheimer’s disease.
