Charak Samhita
वामपार्श्वाश्रितः प्लीहा च्युतः स्थानात् प्रवर्धते। शोणितं वा रसादिभ्यो विवृद्धं तं विवर्धयेत् ॥३६॥
॥ Samprapti of plihodara॥ Afflicted by the jerky movements of the body etc, the spleen located in the left side(flank or left hypochondriac region) enlarges and descends to cause enlargement of the abdomen; or else, a variety of dietary factors leading to increment and morbidity of rasa, rakta etc. which in turn causes enlargement of the spleen. Enlarged spleen distends the abdomen causing plihodara
