“Ustrakantaka,” the botanical source of which is Echinops echinatus Roxb., is a wild branched xerophytic herb. It has a long history of use in traditional medicine, primarily valued for its stimulant properties in addressing sexual dysfunction and debility. The roots (mula), leaves (patra), flower (pushpa) and bark (twak) are frequently employed in folklore and Ayurveda. This plant exhibits multifaceted therapeutic potential, addressing urinary, liver and gynaecological disorders while also demonstrating antimicrobial, analgesic, antioxidant and anti-inflammatory properties. The plant’s pharmacological activities are rooted in its diverse phytochemical profile, featuring the flavonoid apigenin and apigenin-7-O-glucoside, the phenolic compound Echinacin and the alkaloid Echinopsine. The present literature review provides an in-depth examination of Echinops echinatus, synthesising contemporary research on its historical context, ethnomedical application, pharmacognosy, phytoconstituents, pharmacological action and biological activity of the plant.
Ethnomedicine, Flavonoids, Gynaecological disorders
Since the dawn of human civilisation, diseases, disability and death have co-existed with life, as has the quest for positive health, happiness and longevity. With the gradual illumination of human intellect, materials that are safe and can be easily procured from natural surroundings have become a popular source of medicine for longstanding, emerging and reemerging infectious and non infectious diseases. Since then, Audhbhidadravya (drugs of vegetable origin) and their phytoconstituents have been the mainstay of the traditional systems of medicines (1). According to data published recently in the World Health Organisation (WHO) health bulletin, traditional medicines are the mainstay of primary healthcare delivery and their demand is increasing throughout the world, especially in rural populations (2).
The global resurgence of interest in herbal products entails multidisciplinary scientific research activities not only on known but also on many lesser-known medicinal plants. One such obscure medicinal plant with multifaceted health benefits is Ustrakantaka, the botanical source of which is Echinops echinatus Roxb. Echinops originated from the Greek word “echinos,” which signifies a hedgehog or sea urchin; both are spiny animals and the word “echinatus” means prickly. Thus, the name of the plant signifies its thorny appearance of the plant. It is an annual xerophytic herb (3). It has been mentioned in Ayurvedic literature In jwara chikitsa, ashmari chikitsa, masurika chikitsa, etc. It has a bitter and pungent taste (katu-tikta rasa), a pungent post-digestion effect (katuvipaka), is hot in potency (ushnavirya) and alleviates deranged vata-kaphadosha (4).
Anti-inflammatory, antioxidant, reproductive health tonic, antidiabetic, hepatoprotective and analgesic are some of the pharmacological properties exhibited by the plant (5). Echinacin, apigenin-7-O-glucoside, Echinaticin, Echinopsine, taraxasterol acetate and lupeol are the most important documented phytoconstituents present in it (6). It is also a popular folklore dravya used by local vaidyas, Siddha practitioners, tribal people and traditional healers. In India, it is commonly used as a sexual stimulant, both orally and topically and is also practiced for impotence, hoarse cough, dyspepsia, hysteria, syphilis, scrofula, ophthalmia, chronic fever and inflamed and painful joints (7).
The age-old medicinal wealth and traditional knowledge are steadily depleting, so it’s high time to explore lesser-known, easily available, cost-effective, potent ethnomedicinal plants with practical utility in place of rare, endangered and threatened drugs. The present review offers insight into the nomenclature, classical literature, botanical identity, distribution, ethnomedicinal significance, pharmacological activities and therapeutic uses of this plant.
Classical Ayurvedic literature, such as the Charak Samhita, Sushrut Samhita, Nighantus, Ayurvedic Pharmacopeia of India and The Reviews on Indian Medicinal Plants, as well as databases including Google Scholar, the National Action for Mechanised Sanitation Ecosystem (NAMASTE) portal, PubMed, Science Direct, Scopus, Web of Science, the AYUSHDHARA portal and the Cochrane Library, were searched for data collection. The keywords used for the database search include “Echinops echinatus or/and pharmacognosy,” “Echinops echinatus,” “echinops,” “Ustrakantaka,” “Usnakantak,” “Brahmadandi,” “Utkanto,” “Folklore,” “ethnomedicinal use,” “phytochemical,” and “globe thistle.” A manual search of authentic databases was performed to broaden the search spectrum of the study.
1. Vernacular names: The plant is well known as Indian Globe Thistle or Camel’s Thistle in English and as Utakatira, Untakanta, Oontkatara and Brahmdandi in Hindi. Kadechubak, Batresh and Shuliyo are its prevalent names in Maharashtra, Odisha and Gujarat (8).
a Synonyms and nomenclature: The word Ustrakantaka signifies that camels eat this spinous herb. In classical texts of Ayurveda, Ustrakantaka is referred to by many synonyms, such as Uttakantak, Uttkanta (herb with abundant thorns), Rakta, Raktapushpi and Lohitpushpi (plants bearing red-coloured flowers), Varnapushpi (plants having coloured flowers), Kantakphal (fruits bearing thorns), Kantalu (plants with many thorns/bristles), Karmadan (it pierces the hands when touched), Tikshnagra (the branches have sharp ends) and Vrittaguccha (signifies the discoid shape of clustered flowers) (9).
b Geographical distribution: Echinops is mainly available in Afghanistan, Africa, Southeast Asia and the Mediterranean region of the world. In India, it grows extensively in Maharashtra, Gujarat, Rajasthan, Odisha, Karnataka and other dry regions of Andhra Pradesh, up to an altitude of 5,000 feet (10).
c Morphology: It is a xerophytic branched herb reaching a height of 30-60 cm. The branches are covered with white cottony pubescence. Leaves are arranged alternately, non petiolate, oblong to lanceolate, extensively pinnatifid, 8-12 cm long, spinescent, pale above and pubescent beneath. The margin is sinuate, pointed and spinous, with spines about 2 cm long. Flowers are borne at the terminal ends of branches as solitary florets united together into compound globose heads. The heads are purplish-white, compact, with a diameter of 2-3 cm, attached to a stout peduncle, bracteate and spinescent. Involucres bear sharp spines, resemble yellow-coloured pappus hairs and form cylindrical brush-like structures over the achene. Outer involucre bracts are glabrous and oblanceolate, with intermediate bracts (1 or 2) turning into sharp spines of about 2.5 cm. The innermost bracts (5-8) are connate into a tube for more than half of their length. Free segments are acute–obtuse, ciliate, with a laciniate apex and have scarious margins. The anthers are tailed and fimbriated. Fruit cypselae have a short brush-like pappus over them. Achenes are about 4 mm long, densely villous and obconic. The roots are cylindrical, brown-coloured, tough, rough and tortuous (Table/Fig 1),(Table/Fig 2) (11).
2 Review in ayurveda: Ustrakantaka has been mentioned in the Charak Samhita as a component of Chandanadi taila in Jwara chikitsa (12). In the Sushrut Samhita, it is prescribed for the treatment of Ashmari (calculus) (13). The plant is well described in Ayurvedic lexicons, such as in the Karviryadi varga of Raj Nighantu, the Lakshmanadi varga of Shodhal Nighantu and the Sahadevyadi varga of Nighantu Adarsha (9),(14),(15). Chakradutta advised using the plant for Masurika (pustular eruptions) and Lingsthamban (erectile dysfunction) (16).
a Rasapanchaka (Ayurvedic pharmacodynamic principles): Ustrakantaka has Laghu-Ruksha guna, Tikta-Katu rasa, Ushna virya, Katu vipaka and is predominantly Kapha-Vata shamak. The seeds possess Guru and Sheet Guna, Madhur Rasa, Madhur vipaka and Sheet Virya (cold potency).
b Action and indications: Classical lexicons, including Rajnighantu, Shodhal Nighantu, Nighantu Ratnakar and Nighantu Adarsha, have articulated the properties and uses of Ustrakantaka (13),(14),(16),(17). The plant is recommended to be prescribed for Aruchi (anorexia), Hridyaroga (heart ailments), Prameha (diabetes), Mutrakricchta (dysuria), Trishna (thirst), Bandhyatva (infertility), Kasa (cough), Dourbalya (generalised weakness), Vishphotaka (boils), Prasav (labour pain), Mukhadantaroga (oral cavity disorders), Netraroga (eye diseases) and Yoshapasmar (hysteria). It is Deepana (digestive), Ruchya (taste enhancer), Mutral (diuretic), Poustika (nutrient), Vrishya (aphrodisiac), Ropana (wound healer), Shigraprasavkarak (facilitates delivery), Kasaghna (antitussive), Cakshushya (improves vision), Jantughna (antihelmintic), Raktashodhaka (blood purifier) and Hridyarogahara (pacifies cardiac ailments) in karma.
3 Ethnomedicinal and therapeutic relevance: Ustrakantaka is widely practiced as a medicinal herb among ethnic groups, tribal communities, local vaidyas and traditional practitioners throughout India. Tribal communities use its leaves, root bark, flowers, seeds and aerial parts in the form of powder, juice, paste, ash, decoction and infusion for various systemic illnesses. The ethnomedicinal uses of Ustrakantaka are summarised in (Table/Fig 3) (18),(19),(20),(21),(22),(23),(24),(25),(26),(27),(28),(29),(30),(31),(32),(33),(34),(35),(36).
a Chemical constituents: Preliminary phytochemical studies conducted on the plant extracts revealed that flavonoids, alkaloids, glucosides, glycosides, phenolic compounds, saponins, triterpenoids and sterols are the major phytoconstituents present in the aerial parts, seeds, roots, flowers and whole plant of Ustrakantaka. The details have been collected from various databases such as PubChem, Indian Medicinal Plants, Phytochemistry And Therapeutics (IMPPAT) and research articles and are summarised in (Table/Fig 4) (37),(38),(39),(40),(41),(42),(43).
4. Research studies conducted:
a) Pharmacognostical studies- Few studies have been reported so far that feature the pharmacognostical aspects of Ustrakantaka. Organoleptic characteristics, gross macroscopy and microscopic characterisation of the root, stem and leaves were conducted (44),(45). A pharmacognostic evaluation of the root revealed one to three layered cork cells with irregularly shaped parenchyma, a 20-30 layered parenchymatous cortex, a single-layered endodermis and pericycle. The vascular bundles are open, endarch and divided by medullary rays (46). The transverse section of the stem showed the presence of the outermost epidermal layer surrounded by a thick cuticle and uniseriate multicellular trichomes. The cortex is heterogeneous with collenchymatous and parenchymatous cells, a single-layered endodermis, endarch vascular bundles and pith cells containing spheraphides (47). The transverse section of the leaves comprises a single-layered epidermis covered with cuticle and trichomes, a two-layered mesophyll differentiated into palisade and spongy parenchyma and a 3-5 ridged midrib containing endarch vascular bundles (48).
b) In-vitro, In-vivo pharmacological studies- The plant has been studied for its anti-inflammatory, antidiabetic, antifertility, antimicrobial, antioxidant, diuretic, analgesic, hepatoprotective and antiulcer activities, as enumerated in (Table/Fig 5) (49),(50),(51),(52),(53),(54),(55),(56),(57),(58),(59),(60),(61),(62),(63).
c) Toxicity studies- Acute oral toxicity studies of Ustrakantaka root and whole plant extracts were conducted in rats and mice. The studies revealed that its extracts are non toxic in nature and do not reflect behavioral changes or mortality, even up to doses of 2000 and 3000 mg/kg body weight (49),(50),(57),(64).
Ustrakantaka offers a wide array of medicinal properties, which are substantiated by its diverse therapeutic uses in traditional practices by various ethnic groups. The data reviewed herein show that Ustrakantaka plays a vital role in treating disorders of deranged Kapha and Vata dosha, such as kasa, hridyaroga, prameha, prasav, vrana-apachi, mukha-danta-netraroga, agnimandhya, trishna, mutrakrichta, jwar and klaibyata. According to the Ayurvedic pharmacodynamic principle, Ustrakantaka pacifies Vata dosha due to its Ushna virya and Kapha dosha due to its ruksha guna, katu vipaka and ushna virya, thus alleviating Vata and Kapha disorders. Furthermore, its seeds have immense medicinal importance in impotency and seminal debility due to their vrishya and shukrala properties.
However, while the plant has been referenced in classical Ayurvedic and Unani literature for a long time, it remains largely unexplored in the scientific domain. Although some of its ascribed uses in Ayurvedic classics have been scientifically validated through pharmacological studies conducted so far, confirmatory research trials are still required to validate these claims in preclinical and clinical settings. Limited data is available concerning the molecular mechanism of action, analytical and pharmacokinetic studies, as well as the acute and chronic toxicity profiles of the various useful parts of the drug, highlighting the need for rigorous research trials.
Ustrakantaka has been a pivotal traditional medicine, particularly in rural areas, where it is used in the treatment of common ailments such as hoarse cough, dysuria, seminal debility, dyspepsia, hysteria, difficult labour, inflammatory diseases, wounds, scrofula, joint pain, fever and as a nervine tonic. The plant is relatively safe, potent, easily accessible and affordable to stakeholders. Thus, initiatives to bring this unexplored plant into mainstream practice, supported by evidence-based research, are the need of the hour.
