One study found that the anti-oxidant and anti-inflammatory effects of the leaves and twigs of the bas cedar protected gastric mucosa against the effects of non-steroidal anti-inflammatory drugs (NSAIDs), which are often prescribed for arthritis and other painful conditions.

Recent research has highlighted the broad benefits of one particular chemical procyanidin B-2, which has shown promising signs of anti-tumour and anti-cancer properties and could also be effective in lowering blood pressure. Other research has confirmed that procyanidin B-2 can increase hair growth, which is one of the traditional uses for bas cedar.
