Ashoka health benefit
Botanical name for ashoka is Saraca Indica or Jonesia Ashok. Ashoka is an Ayurvedic herb.
As of July 2009, no human studies with Ashoka herb could be found on Medline.

Screening of natural products for mosquito larvicidal activity against three
major mosquito vectors Aedes aegypti, Culex quinquefasciatus, and Anopheles
stephensi resulted in the identification of three potential plant extracts viz.,
Saraca indica / asoca, Nyctanthes arbor-tristis, and Clitoria ternatea for
mosquito larval control. In the case of S. indica / asoca, the petroleum ether
extract of the leaves and the chloroform extract of the bark were effective
against the larvae of C. quinquefasciatus. Among the three plant species studied
for mosquito larvicidal activity, C. ternatea was showing the most promising
mosquito larvicidal activity. The phytochemical analysis of the promising
methanolic extract of the seed extract was positive for carbohydrates, saponins,
terpenoids, tannins, and proteins. In conclusion, bioassay-guided fractionation
of effective extracts may result in identification of a useful molecule for the
control of mosquito vectors.
Saracin, a seed integument lectin from ashoka, has immune influencing
potential.

Saracin, a seed integument lectin from Saraca indica Ashoka has been found to be
mitogenic for human lymphocytes, and this mitogenic activity could be inhibited
in presence of fetuin. Further, treatment with saracin could induce secretion of
IL-2 in a culture of resting human peripheral blood mononuclear cells. Saracin
has a higher affinity for the CD8(+) than CD4(+) T cells. Lymphocytes cultured
under different conditions has shown that this lectin could induce apoptosis in
activated T-lymphocytes. Saracin seems to be an interesting
immunomodulator for the mammalian immune system.
Flowers & flower buds of Ashoka Saraca indica Linn have antibacterial activity.
