Svalpa Triphala = Kayaphala, Khadira, Parushaka.
Do not confuse this with the "Trimada" (Vidanga, Musta, Chitraka) or "Trikatu" (Shunthi, Maricha, Pippali).
Step 1: Recall Triphala variants. Classical texts describe more than one Triphala group depending on the three drugs combined Step 2: Recall Svalpa Triphala. Svalpa, or lesser, Triphala is composed of Kayaphala, Khadira and Parushaka rather than the common Haritaki-Bibhitaki-Amalaki trio Step 3: State the answer. So Svalpa Triphala consists of Kayaphala, Khadira and Parushaka \[ \boxed{Kayaphala + Khadira + Parushaka} \]
