Comments, has no relation to the poisonous plant, hemlock, that was used to trick Socrates 
 - if bark is turned into powder, it can be used in shoes to eliminate foot odor 
 -  Native Americans used its inner bark raw or cooked and dried and ground into powder to be mixed with cereal flour for bread, or to thicken soups and stews. The inner bark was harvested in spring and dried for winter use when food was scarce. The leaves and twigs of the Western Hemlock yield an oil known as “spruce oil” which is used commercially to flavour chewing gum, ice-cream and soft drinks - http://herbs-treatandtaste.blogspot.ca/
