Wan Chang-Ngang

Ritual purpose

Metta, protection, house auspiciousness, stunning/confusing thieves or hostile people (จังงัง), enemy non-hostility, and (per BanVanThai) คงกระพันชาตรี.

Botanical

Kaempferia parviflora Wall. ex Baker per BanVanThai; also a local name for กระชายดำ. BanVanThai's description of white inner flesh conflicts with standard K. parviflora's purple-to-black flesh — botanical form confusion remains.

Origin / legend

No origin legend; BanVanThai cites several old waan manuals as textual sources without a discovery story.

Consecration method (ปลุกเสก)

Grind the rhizome into powder; mix with face powder, beeswax, sandalwood oil, or fragrant oil; carry or anoint forehead/lips. Source states the powder "must be consecrated" with the given katha; a coercive household-water use is also reported but should be treated as historical folk-magic documentation only.

Katha (คาถา)

• อิสวาสุ สุสวาอิ จิเจรุนิ พุทธะสังมิ นะชาลิติฯ

  i-sa-wa-su su-sa-wa-i chi-che-ru-ni phuttha-sangmi na-cha-li-ti

  Syllabic Thai-Pali charm formula prescribed for empowering the powder; exact lexical meaning unclear.

Application

Plant at home for protection and luck; carry powder; anoint forehead/lips; mix into face powder, beeswax, sandalwood oil, or fragrant oil.

Taboos / restrictions (ข้อห้าม)
