Cinnamomum subavenium

Cinnamomum subavenium ranges from Bangladesh and Myanmar to southern China, Vietnam, Cambodia, Peninsular Malaysia, Sumatra, Borneo, and Sulawesi.^[3]

In Borneo it is found in Sarawak (Marudi and Sri Aman districts) and Sabah (Ranau, Tambunan and Sipitang districts) in Malaysian Borneo, and West Kalimantan in Indonesian Borneo. It grows in mixed dipterocarp and lower montane forest to 1500 metres elevation.^[4]

Leaves of Cinnamomum subavenium are an important spice.^[2] It is also a Chinese herb that has been suggested for use as a skin whitening agent. The plant contains substances which inhibit production of tyrosinase an enzyme which catalyzes the production of melanin. The herb has not been established as either effective or safe but is being researched by Hui-Min Wang and his colleagues at Kaohsiung Medical University in Taiwan where experiments shown that it was effective at causing zebrafish to lose their stripes.^[5]
