Yield, densities:
Access rules:
Sustainability: Minimum harvestable size of the stems is a diameter of 2 cm or
more, which takes 3-5 years to grow (Champasak, 1 village). Because of its
easy regeneration and colonising behaviour in disturbed forests the species becomes not easily endangered.
Conservation status: Female plants are rare.
Processing: Before use drying in sun is required and storage in
ventilated place. Stems are cut in small pieces and scraped, then
infused in boiling water. The stem is also dried in the sun for 3-4
days and pounded to a powder and used as quinine.
Quality criteria: Under ambient and cooled conditions stored crude
stem extracts maintain their pesticidal activity for 3 months.
Marketing: Stem parts or powdered stems can be found frequently
on local markets for US$2/bundle and some trade with Thailand.
There is a potential to export ca. 100 tonnes against a price of
US$1.5-5/kg.
Market prospects: Sold through e-commerce in Thailand, US$2 per 85 gram, container of capsules. Khua khao ho
has proved to have many interesting properties confirmed by modern research. Believed is it has good prospects to
play a larger role in modern medicines in other parts of the world. Also, its safe pesticide use has been proven
effective.
Propagation: In India and Thailand cultivated as a medicinal plant. Vegetatively propagated. Stems remain viable
when cut into pieces because dried sap effectively closes the cut ends, stored to up to 1 year in a closed box.
Propagation by seed is possible.

environment. Strong regeneration capacity, abundant in secondary regrowth, climbing in canopy. Grows on granite
and shale bedrock.
