Plants of the Opuntia family have been used for ages by Native Americans as natural and organic fortifying and bonding agent in cement-less construction methods. You’ll see it sprayed on dirt paths to create a hard surface. It’s used on dirt airfields. It can be strained for only the liquid (glue like bonding agent), in combo of liquid and pulp (mixed with dirt and gravel to form a natural concrete), or peeled and diced to add zing to guacamole. []
