Wan Naresuan

Ritual purpose

Primary: khongkraphan/invulnerability and battlefield weapon protection. Secondary: danger protection, protection from khun-sai and ghosts/spirits.

Botanical

Boesenbergia cf. petiolata Sirirugsa, local name "เช้าพัน" in Saraburi; a small ginger ~15-50cm with white flowers reddish near the lip. FarmSSB places it in the "เพชรกลับ" group because roots grow backward/upward; green and dark/black forms exist, the dark more sought-after.

Origin / legend

FarmSSB's legend: used since Ayutthaya times, specifically by King Naresuan to boil/prepare oil for coating spears and swords before battle, and for bathing/eating for invulnerability — hence the name. A cautionary lore-claim says excessive ingestion may have contributed to his death from poisonous overuse; reported plant lore, not verified history. A forum follow-up found no independent corroboration of this exact plant-death claim, and turned up a directly competing community claim instead: a Palungjit poster, citing personal spiritual contact, says Naresuan was poisoned (by another party), not killed by waan overuse — the two claims actively contradict each other and should both be presented as unverified community lore, not history. A separate Palungjit thread preserves an adjacent, non-herb-specific motif: that the monk Maha Thera Khanchong consecrated holy water for King Naresuan's daily face-washing and that Naresuan's body was darkened by martial training and "bathing in waan" generally — broader cultural background, not evidence for this specific herb.

Consecration method (ปลุกเสก)

Regularly consecrate the watering water with "นะโมพุทธายะ". As a phet-klap type herb: before taking the rhizome for magical use, set "นะโม" 3 times, recollect the Triple Gem, recite the backwards-Itipiso katha.

Application

Boil/prepare oil to coat spears/swords before battle; bathe or soak in waan; eat for invulnerability (lore only, not a safe-use instruction); keep in the house or carry for protection.

Taboos / restrictions (ข้อห้าม)

• Partial shade, moist but never soggy; reduce watering during dormancy without letting the tuber dry out fully. Source itself reports a poison/over-ingestion warning — do not present eating as harmless.
