Origin / legend

Baanlaesuan gives real folk belief: crossing the vine in the forest may cause a person to become lost, requiring คาถาเบิกไพร to get out. NanaGarden seller text expands this as forest occult plant lore known to hunters.

Consecration method (ปลุกเสก)

No full empowerment procedure beyond carrying the dry vine. Seller text gives short formulas only and says full katha is supplied to buyers; root can also be ground with sandalwood oil, น้ำมันแก้ว, or beeswax for mouth/lip use.

Katha (คาถา)

• นะโม พุทธายะ / อิธะคะมะ / โอมมหาหลง

  namo phutthaya / i-dha-kha-ma / om maha long

  Short formulas only, not a full katha: "homage to the Buddha"; an unclear syllabic charm; "Om, great longing/delusion".

Application

Plant in front of house/shop or train as a vine/arch; carry dried vine; use in sacred powder, amulets, or charm mixtures.

Taboos / restrictions (ข้อห้าม)

• Folk warning: avoid carelessly crossing the vine in forest, as it may cause getting lost; the exit katha (คาถาเบิกไพร) is not given in sources.
