Charak Samhita
निदानाकृतिसंसर्गाच्छ्वयथुः स्याद्द्विदोषजः। सर्वाकृतिः सन्निपाताच्छोथो व्यामिश्रहेतुजः ॥१५॥
As mentioned earlier, there is a combination of causes and symptoms of two dosha, called dwidoshaja. A sannipataja swelling, on the other hand, combines the causes and symptoms of all the three dosha.
