Taiwan mountain longan

Helicia formosana

Helicia formosana is a plant native to low-altitude mountain forests, particularly in regions influenced by environmental factors such as stream distance and topography. While there are no traditional uses recorded for this species, it has been noted for its role in the ecosystem, with two new species of insects described that have host-plant associations with Cinnamomum camphora and either Helicia formosana or Prunus campanulata. Scientific evidence suggests that nutrient content, including water, crude protein, calcium, and phosphorus, influences feeding choices by Assamese macaques in limestone forests. Increasing typhoon frequency has also been observed to alter the ecosystem structure and function in subtropical forests where Helicia formosana is found. No significant safety issues or drug interactions have been recorded for this plant.
