1. Bacterial infection : Plant part used: Root.
   According to Habbu P (2009): speciosa root was studied against bacteria, fungi & Mycobacterium tuberculosis H37 Rv sensitive strain by in vitro & in vivo assays. A synergistic effect between flavanoids sulphates & commercially available antitubercular drugs was observed with FIC index of 0.443 +/- 0.245, 0.487 +/- 0.247 for isoniazid & 0.468 +/- 0.333, 0.417 +/- 0.345 for rifampicin, whereas EAAS fraction showed partial synergistic effect.
2. Oxidative stress : Plant part used: Root.

Improvement in stress markers may be due its prolong effect of resistance to stress & partly due to free radical scavenging activity.
3. Diabetic ulcer : Plant part used: Sheet.
