Other possible solutions: d-limone In one unpublished trial, subjects took one gram of d-limonene every other day for 20 days, on an empty stomach (that is, half an hour before eating or an hour afterward). A third of them experienced relief from their heartburn after a single capsule, and within two weeks 90 percent had relief. After a single course of treatment, relief lasted for up to six months.
Licorice The natural solution for ulcers, deglycyrrhizinated licorice root (DGL), can also be an effective acid reflux treatment. The suggested dose of DGL is two tablets, chewed about 20 minutes before meals, three times a day, or it can be taken shortly before bedtime if you suffer mostly from nighttime acid reflux. Use only chewable DGL—it must be mixed with saliva in order to be effective.
