Acacia Concinna (Sompoy): Role in Rituals and Local Beliefs of Lanna

Abstract

This article explores the cultural significance of Som Poi (Acacia concinna) in the context of Lanna traditions, particularly its role in rituals associated with the purification of misfortune. Som Poi is not only a traditional medicinal plant with pharmacological benefits and practical daily uses, but also holds profound spiritual meaning. It is considered a sacred plant linked to the release of misfortune and the rejuvenation of life force. This belief is reflected in the use of Som Poi pods in various rites, such as sadoh kroh (misfortune-lifting ritual), rod nam dam hua (water-pouring rite of respect), and life transition ceremonies such as birth and death. The body of knowledge surrounding Som Poi thus encompasses botany, traditional medicine, and cultural beliefs. It serves as a symbolic bridge between nature, belief systems, spirituality, and the local wisdom of Lanna, highlighting the deep-rooted connection between humans and nature, and the continuity of culture through rituals embedded in the everyday life of the Lanna people.
