Rosemary compound shows promise against Alzheimer's disease

Researchers in California have developed a stable form of carnosic acid, a compound found in rosemary, which shows promise in treating Alzheimer's disease. This new derivative, called diAcCA, improved memory and reduced inflammation in mouse models. Mice treated with diAcCA exhibited increased neuron synapses and decreased toxic protein levels associated with Alzheimer's. The compound was absorbed better than pure carnosic acid and reached therapeutic levels in the brain quickly. While results are encouraging, clinical trials are needed to test diAcCA's effects in humans. The researchers believe this compound may also help treat other inflammation-related conditions.
