Historical Usage:   Kansas or wild sage, plant in the Mint family, has the reputation of being an excellent remedy in the cure of fever and ague (the shakes.)  (Source: www.henriettesherbal.com/eclectic/journals/net1882/net-1882-kansas6.html)

The name is derived from the Latin salvere ("to save"), referring to the long-believed healing properties of salvia. The Latin was corrupted to 'sauja', the French 'sauge', and the old English 'sawge', and eventually became the modern day 'sage'.

Recent Usage: Bio-Resonance Scanning has revealed it to be highly beneficial in addressing the accumulation of ammonia in the brain tissue as seen in cirrhosis of the liver, hepatitis, and the local accumulations in the brain as seen in neurological Lyme disease. Salvia Azurea is also beneficial for clearing nitric oxide (NO), the metabolite of ammonia in the musculoskeletal system.  Nitric oxide accumulates in the joints and muscles in reaction to Borrelia burgdorferi and other Borrelia strain spirochetes, which release ammonia which is almost instantly converted into nitric oxide. 

Nitric oxide causes a hyper-inflammatory response in the tissues leading to fibrin accumulation, joint and muscle pain and stiffness, as well as potentially increasing the production of the thick fibrin-coating of tumors.   

Correction: We first mistakenly named this plant Pale Spike Lobelia. These pictures below show how the mistake was made; these two plants are very similar.
