BOTANICAL NAME         : Saraca indica Linn.

                                                  Saraca asoca Roxb. De. Wilde

FAMILY                           : Fabaceae

 

Regarding the drug at hand, a clear description from Atharva Veda Parishishta indicates that Ashoka is known to Indians since vedic literature.

Charaka described it as an anodyne while Sushrutha mentioned it under Rodhradi guna. In this context , it is very important to note that Ashoka is not reported as an emmanagogue , oestrogenic or uterine tonic as claimed by the herbal industry. It is having styptic property like ergot preparations and it exhibits potent oxytocin like activity. Therefore one must be cautious while using its bark in therapeutics.

At present P. longifolia is popular as Ashoka tree since it is widely grown in the gardens. But the original material is also available abundantly.

 

 

 

 

LITERARY REVIEW

 

Charaka described it as an anodyne while Sushrutha mentioned it under Rodharadhi guna. Vrinda Madhava for the first time indicated it in Rakta Pradara. Vanjula is supposed to be the synomyn of Ashoka as well as Tinisa. Under Nyagrodhadi guna it will be wise to accept vetasa instead of Ashoka.

RESEARCH

 

  1. The effect of the administration of an extract of bark was studied in mice that were treated with a dose of 2 mg / kg of cisplantin i.p for 5 days. The extract of bark partially prevented the decrease in body weight, hemoglobin levels and leucocytes counts caused by 2 mg / kg of cisplantin. The i.p administration of bark extract also significantly prolonged the life span of cisplantin treated mice almost 3 fold. In contrast, an extract of flowers only tended to protect from cisplantin induced falls in hemoglobin levels and leucocyte counts.
  2. Flower extract administered orally indicated 50% in Dalton’s lymphoma indicated ascites and sarcoma 180 tumour cells at a concentration of 38 micrograms and 54 micrograms respectively with no activity against normal lymphocytes but preferential activity for lymphocytes derived from leukemia patients.

 

 

 

  1. Flower bud extract inhibited such Esch. Coli, Salm.viballerup, Vibrio cholerae, Shigella dysenteriae and Shigella boydii and this inhibition were stronger than that of flower extract.
  2. A phenolic glycoside P2 showed highly potent and specific oxytocic activity in vitro and invivo on uteri of rat and isolated human myometrial strips and fallopian tube. P2 was active in remarkably low concentration and nontoxic to animals up to 250 mg/ kg.
  3. 2 crude glycosides isolated from bark exhibited uterine spasmogenic activity, both showed significant stimulant action on isolated uteri of rat, guinea pig, rabbit, dog and human, pure phenolic glycoside P2 was highly potent and showed consistent oxytocic activity.
  4. Ashoka stimulated the uterus making the contractions more frequent and prolonged without producing the tonic contractions like ergot or pituitary. It should therefore be proved useful in all cases of uterine haemorrhages, where ergot is indicated viz. menorrhagia , metorrhagia, post partum hemorrhage etc.
