Overview

Oleander is one of the herbs traditionally used in Ayurveda for ulcers. Karavira is Ayurveda's poison-as-medicine: Nerium oleander, all parts cardiotoxic from oleandrin. Root paste treats Kushtha, ringworm, and stubborn ulcers, externally only.

How Oleander Helps with Ulcers

According to Ayurvedic pharmacology, Oleander has specific properties that make it valuable for addressing ulcers:

Potency (Virya): Ushna (hot)
Post-digestive (Vipaka): Katu (pungent)
Taste (Rasa): Tikta (bitter), Katu (pungent)
Qualities (Guna): Laghu (light), Tikshna (sharp)
