Add "brain food" to that VeganBlogger list!
According to a collaborative group from the Burnham Institute for Medical Research in La Jolla, California and Japan, rosemary fights free radical damage in the brain. So published on News Medical 2007 October.
The research report states that the active ingredient in rosemary, known as carnosic acid, can protect the brain from stroke and neurodegeneration that is due to injurious chemical free radicals. I think that matches "mood elevation" on the health benefits list.
Rosemary is a frequent ingredient in spa items, like soaps and aromatherapy blends. Also, this herb is a culinary delight. Chic Eco Catering favors it for roasted potatoes.
Rosemary grows exceptionally well in lower Puna and from what I understand, all over Big Island. Dirt is necessary, but once established, it is compatible with lava rock.
The blue blossoms are lovely, but I do wonder if flowers are more profuse in higher altitudes. They certainly grow into large lovely bushes in Pahoa though.
Haven't built a rosemary nursery, but buyers are welcome to contact me for healthy plants at $5 each. Same 6-inch size usually sells for $10. Advance ordering recommended.
