Bottlebrush is a deep cleanser of the bowel. Its supportive energy helps to clear away the past so we can leave it behind us and move forward unfettered as we ascend to our highest self.
As a red essence, this essence is a fiery one, and is taken with caution and in small doses. 
This essence helps to clear the Root Chakra, so that balance may be restored where there was perhaps some disturbance in the past (i.e. deep feelings of insecurity, of not belonging, fears and anxieties).
