Similar attitudes have also been observed in hypertensive patients using lemon juice. Lemon juice or formulas contain- ing lemon juice are recommended by several sources includ- ing websites. ‘I began to use lemon juice, can I discontinue my drugs’ is a typical patient question that can be seen in relevant websites. Websites indicating lemon juice does not affect BP are also present. In the internet era, it is impossible to know and control that which sources will the patients read or which websites or publications will affect the patients’ be- haviours. Patient education is the most effective method to cope with potential problems arising from lemon juice us- age and must be an important and compulsory part of therapy programs as mentioned by hypertension guidelines (Choba- nian et al., 2003;; Mancia et al., 2007). In conclusion, there is no evidence that lemon juice lowers BP at the present time and more studies are needed to investigate the effect of lemon juice on BP and possible interactions between lemon juice and drugs. Physicians should keep in mind that alternative therapies can have risks and train their patients about compli- ance to the treatment.
