Introduction
Ashoka botanically known as Saraca asoca is an auspicious tree with various medicinal properties. Saraca asoca is a vulnerable species that is becoming rarer in its natural habitat but is cultivated throughout India. Saraca asoca is a sacred plant for Hindus as it is worshiped every year on the 27th of December for the Hindu God of love Kamadeva. Also, it was believed that Gautam Buddha the founder of Buddhism was born under this tree. The word Ashoka is derived from the Sanskrit word A and Shoka which give it the deep meaning that is freedom from grief or one that helps to achieve happiness. Ashoka trees consist of various chemical constituents like glycosides, tannins, saponins, flavonoids, etc due to which Ashoka tree exhibits various properties like oxytocic property, anti- implantation, anti-bacterial, anti-cancerous, uterine tonic activities, etc.

Historical background of Ashoka
A clear description from Atharva Veda Parisista indicates that Ashoka is known to Indians since Vedic literature. It is also mentioned that Asoka bears red flowers (A. Pa. 21/7/3). Charaka described it as an anodyne while Shusruta mentioned it under Rodradhi Gana. In the earlier texts, it is not described as Pradara/ Rakta Pradara. Vrinda Madhava for the first time indicated it in Rakta Pradara. Ashoka is having a styptic property like ergot preparations, and it exhibits potent oxytocin-like activity. Therefore, one must be cautious while using its bark in therapeutics. Fortunately, it is being adulterated with the barks of Polyalthia longifolia or Shorea robusta, or Bauhinia variegata and therefore the side effects with larger doses are not reported. Vanjula is supposed to be the synonym of Asoka as well as Tinisha. Under Nyagrodhadi Gana it will be wise to accept Vetasa instead of Ashoka. Salix caprea Linn is identified with Vetasa by Bapalalji. At present, P. longifolia is popular as an Asoka tree since it is widely grown in the gardens, but it is false (Nakali) Ashoka.
External morphology of Saraca asoca
Ashoka is a tree that grows 6-9 meters in height, with glabrous branches.
- Leaves- Leaves of Ashoka tree are 15-20 cm long, compound leaves, rachis glabrous, corky at the base, petioles very short, stipules are interpetiolar, completely united.
- Leaflets- Leaflets of the Ashoka tree are 4-6 in pairs, 10-20 cm long and 4-7 cm wide, oblong-lanceolate, obtuse, or acute, glabrous, base rounded, or cuneate, slightly oblique, petioles 4-6 mm long, stout, wrinkled.
- Inflorescence- The inflorescence of the Ashoka tree is Axillary corymb.
- Flowers- Flowers in the Ashoka tree are numerous, fragrant, 7.5-10 cm across, peduncles stout, pedicels 8-13 mm long, red, glabrous, bracts ovate, subacute, bracteoles 2, appearing like a calyx, 4 mm long, calyx passing from yellow to orange and finally red. Tube 1.3-2 cm long, cylindrical, solid at the base, segments 4, oblong or obovate-oblong, 1 cm long. Stamens 7 or 8 ovaries are pubescent.
- Fruit- The fruit of the Ashoka tree is in pod shape, black, 10-25 cm long, 4.5-5 cm wide, linear-oblong, tapering to both ends, compressed, and glabrous.
- Seeds- 4-8, ellipsoid-oblong, 3-8 cm long, slightly compressed.
Flowering and fruiting time
Flowering occurs from March to April and fruiting occurs between August to September.
Distribution of Ashoka
Saraca asoca is found in the Eastern Ghats and the Western Ghats, including Orissa, Maharashtra, Karnataka, and Kerala. The tree is also grown in gardens, throughout India for its attractive bunches of sweetly scented flowers and shade.
Do you know?
Saraca indica Linnaeus is generally mistaken for Saraca asoca (Roxb.) de Wilde, the real Indian Ashok Tree. The former with bracteoles spreading on the pedicel and falling off at length is said to belong to Siam, Malaya, Sumatra, and Java, whereas the latter with erect bracteoles clasping the pedicel is found only in Sri Lanka, India, and Bangladesh. However, since both are closely related, it is worthwhile studying the usefulness of the bark of Saraca indica as a substitute for Saraca asoca whose demand is enormously increasing day by day.
The useful part of Ashoka
Bark, Seed & Flowers.
Bark: The bark of the Ashoka tree is curved, channeled, or sometimes quilled pieces, 5 to 12 mm in thickness. The outer surface is rough, greyish brown, covered with warty protuberances, and enclosing circular to transversely elongated lenticels. The inner surface of the bark is smooth reddish-brown and finely mottled with black dots. The transversely cut surface shows long, radially elongated but irregularly running medullary rays. It is tough to break and becomes fibrous. Ashoka tree bark doesn’t possess any characteristic odor.
Important phytoconstituent of Ashoka
- Bark- The bark of the Ashoka tree contains Catechol, tannins, epicatechin, Catechin, ketosterol, Saponin, hematoxylin, saponin, etc.
- Flowers- Flowers contain beta-sitosterol, Quercetins, Gallic acids, Palmitic acid, Stearic acid, Oleic acid, and Linoleic acids.
- Pods- Pods of the Ashoka tree contain Catechol, Epicatechol, and Leucocyanidin.
- Seeds- Seeds of the Ashoka tree have oleic, Linoleic, Palmitic, and Stearic acids. Wood contains Quercetin.
Substitution and adulteration of Ashoka
Polyalthia longifolia are very commonly used as Ashoka. Shala i.e Shorea robusta is the common substitute for Ashoka.
The bark of the Ashok tree is sometimes mixed with Rohitaka bark and Caesalpinia pulcherrima.

- The phytochemical analysis of the promising methanolic extract of the seed extract was positive for carbohydrates, saponins, terpenoids, tannins, and proteins. Bioassay-guided fractionation of effective extracts may result in the identification of a useful molecule for the control of mosquito vectors.

- The antimicrobial potential of seventy-seven extracts from twenty-four plants was screened against eight bacteria and four pathogenic fungi, using micro broth dilution assay. Water extracts of Acacia nilotica, Justicia zeylanica, Lantana camara, and Saraca asoca exhibited good activity against all the bacteria tested.

- The commonly used adulterant is the bark of Polyalthia longifolia which shows some similarity with that of Asoka. Studies were conducted at the Aromatic and Medicinal Plants Research Station, Odakkali (Kerala Agricultural University) from 2001-to 2002 to evolve methods for differentiating the original drug from the adulterant species by anatomical biochemical and chromatographic techniques.

Vatavyadh (Vataja disorder)- Shusruta prescribes Asoka- Ghrita like Tilvaka Ghrita in Vata Vyadhi. (Shusruta Samhita Chiktsa Sthana. 4/ 27)
Important benefits of Ashoka
- Dysmenorrhea (Kasht Aartava): As per Ayurveda Aartava is governed by Vata Dosha, so Vata must be under control to manage dysmenorrhea. Saraca asoca with its Vata balancing properties reduces abdominal cramps and pain during the menstrual cycle.
- Piles (Arsha): The main culprit behind piles is a sedentary lifestyle, unhealthy diet, and vitiation of Tridosha, mainly Vata. Vata will lead to Vivandha (constipation) as it causes a low digestive fire. All these factors lead to swelling in the veins of the rectum area which lead to pile masses. Ashoka with its Sheet Virya and Vata balancing property reduces discomfort and burning sensation in pile mass, and anus and also relieves the swelling in the vein of the rectum area.
- Leucorrhea (Shweta Pradara): Leucorrhea occurs as a result of an imbalance in Kapha. Ashoka with its Kapha balancing and Kashaya (astringent) properties, controls aggravated Kapha and shows good results in Shweta Pradara.
- Menorrhagia (Rakta Pradara): In Rakta Pradara excessive secretion of menstrual blood occurs due to aggravated Pitta. Ashoka with its Sheet Virya (cold potency) helps to control heavy menstrual bleeding.
Matra (Therapeutic administration and dosage) of Ashoka

- Beeja Churna (Seed powder)- 3- 6grams
