Reading the bitterness
For Tacca chantrieri (also called tashiro-imo, or black cat), a government knowledge page compiling plant knowledge from the northern Thai highlands records that the flowers and young leaves are roasted over fire or blanched for eating, and the roots are decocted as a tonic. The page describes no taste and is not an ethnographic survey, so when, by whom, and in what circumstances the plant is eaten remain unknown.
The same page lists ดีงูหล้า and ดีงูหว้า as northern Thai names for this plant, alongside other names from central and southern Thailand. However, this is only a name match: the page alone has not confirmed whether it is the plant called ดีงูหว้า among the herbs in Lisu Tom Khom. Because the same vernacular name may refer to different plants across regions or communities, the correspondence between name and species remains partly unconfirmed.

Composition and content (3)
Scope: Name-level match only: the HRDI knowledge page lists ดีงูหว้า as a northern Thai variant name for ดีงูหล้า = Tacca chantrieri.
Note: Do not treat this as an identification. The HRDI page covers Thailand generally and gives no Lisu-language name, so the herb called ดีงูหว้า in a Lisu Tom Khom preparation could refer to a different plant. The identification rules and local-confirmation task are recorded in tomkhom-research-dossier.md.

Scope: Thailand; according to a knowledge page from the public agency HRDI that lists local names from northern, central, and southern Thailand.
Note: This is a government knowledge-base record rather than an ethnographic survey, and the page contains no description of taste. Information about Tacca bitterness (taccalonolides, Chen 1988) is bibliographic only and is intentionally not asserted here.
