en Ethnobotanical Study and Distribution of the <i>Solanum</i> Section <i>Solanum</i> Species (Solanaceae) in Iran كشاورزی و اتنوبوتانی Agriculture & Ethnobotany پژوهشی Research <div dir="ltr" style="text-align: justify;"><strong>Background:</strong> <em>Solanum</em> section <em>Solanum</em> has been extensively used in traditional medicine in Iran for many ailment treatments. The plant contains some substances such as total alkaloid, steroid alkaloid, steroidal saponins and glycoprotein, exhibiting anti-tumor activity.<br> <strong>Objective:</strong> In this research, wild species of <em>Solanum</em> section <em>Solanum</em> has been studied in Iran in the field of ethnobotanical investigation such as interviews, questionnaires, scientific articles, authentic books and ancient documents in traditional medicine. The anthropological uses of the plant have also been taken into consideration.<br> <strong>Method:</strong> The wild species of these plants in Iran were studied using field and library methods. In the first method, to determine the distribution of <em>Solanum</em> and its related plants, numerous trips were carried out and many samples were collected. The anthropological use of these plants has been examined through interviews and questionnaires from 39 local people. In the second method, traditional Iranian books and published articles on the subject were also studied. &nbsp;<br> <strong>Results:</strong> According to this survey, these plants are commonly used for food digestion and constipation in traditional as well as current local medicine. In addition, we identified 180 different growing locations in Iran to illustrate their distribution maps.<br> <strong>Conclusion</strong>: These plants are being used as fever-reducing agent, pain-reliever, softener, laxative, diarrhea, anticoagulant and anti-asthma. Some outstanding results are obtained in the treatments of analgesic and sedative, anemia, burns, carminative, constipation, cough, cut restoration, food digestion, infections, mouth disinfection, skin diseases, toothache etc.</div> <div style="text-align: justify;"><strong>Background:</strong> <em>Solanum</em> section <em>Solanum</em> has been extensively used in traditional medicine in Iran for many ailment treatments.
