Scientific studies on health benefits and uses of Red cedar
• Anti-Ulcer / Gastroprotective:
Study of ethanol extract of Toona ciliata showed gastroprotective effect in ethanol-induced and stress-induced ulcers in rats.
• Analgesic / helps relieves pain :
In a study of Indian medicinal plants, the ethanolic extract of Toona ciliata showed the most significant analgesic activity.
• Anti-tumor / Cytotoxicity:
Crude extract study yielded a major isolate, siderin. T ciliata was found to exhibit significant cytotoxicity and mild to moderate antitumor activity. Results were compared to those produced by vincristine sulphate.
In a screening of twelve Meliaceae species for the presence of lectins, Toona calantas was one of eight that tested positive for lectin activity. Studies on lectins show its possible participation in the wound healing process.
