The best things to utilize from the natural pharmacy would be compounds that help to relax and calm you in an effort to reduce the severity of the cravings. In addition, if you are in a more relaxed state of mind, you are less likely to get triggered into a craving in the first place.
L-theanine is a wonderful natural compound derived from green tea that helps to calm the mind without any sedating effects. This may help to promote a relaxed state of mind and reduce the cravings. Adding other herbs like Lemon Balm, Skullcap and Passionflower to the formula would further promote the relaxation effects. The nice thing is that all these natural compounds do not tend to be overly sedating so they can be used during the day or at work without clouding your mind and impairing concentration.
St. John’s Wort has had some limited studies with helping people to quit smoking. It is thought to increase Serotonin levels in the brain which subsequently improves mood and outlook and reduces cravings. If you are not on any other anti-depressants it tends to be very safe and well tolerated. If you have other serious health conditions and are taking prescription medications for it, you should discuss taking St. John’s Wort with your doctor.
