If you just can't say no or if you are over anxious then Bach Centaury is for you. Centaury is one of Edward Bach's Original Flower Remedies homoeopathically prepared from plant flower extract.“ Kind, quiet, gentle people who are over-anxious to serve others. They overtax their strength in their endeavours. Their wish so grows upon them that they become more servants than willing helpers. Their good nature leads them to do more than their own share of work, & in so doing they may neglect their own particular mission in life.”
