Rosemary contains rosmarinic acid and carnosic acid — among the most potent plant antioxidants documented. Specific documented effect on cerebral circulation — rosemary aroma alone has been shown to improve memory performance and cognitive function in research. Directly relevant to the underdiagnosed cognitive decline in aging Black Americans.
Available fresh at most grocery stores year-round, dried everywhere. Grows easily as a potted plant — one plant provides years of fresh rosemary.
Rosmarinic acid inhibits inflammatory enzymes (LOX and COX) — the same pathways targeted by ibuprofen. Carnosic acid is neuroprotective — crosses the blood-brain barrier and reduces oxidative damage to neurons. Research: rosemary aroma increases memory performance by 15% in cognitive tests. Ursolic acid promotes muscle growth and reduces inflammation — relevant for Brothers Sentinel and diabetes management (muscle = insulin sensitivity). Rosemary scalp massages with rosemary oil showed equivalent efficacy to minoxidil for hair growth in a 2023 RCT.
Add fresh or dried rosemary to roasted meats, vegetables, and olive oil. Steep in hot water as an herbal tea (3-4 sprigs, 10 minutes). Add to bone broth. Rosemary-infused olive oil: warm olive oil with fresh rosemary, let cool, store — the finishing oil for any dish.
