Herb's Introduction
The plant in question is scientifically classified as Drimia indica (Roxb.) Jessop, with a significant historical synonym being Urginea coromandeliana Hook.f. or Urginea indica. It belongs to the Asparagus family, Asparagaceae, having previously been categorized under the family Hyacinthaceae. Commonly known as the Indian Squill or Wild Onion, this bulbous geophyte is a perennial herb of immense importance in various traditional medicine systems across South Asia, including Ayurveda, Unani, and Sidha. Drimia indica is highly regarded for its powerful pharmacological properties, particularly its effects on the cardiovascular and respiratory systems. However, it is also notable as a potent herb with inherent toxicity; the bulbs contain cardiac glycosides and are considered an acrid poison if taken in large doses, hence earning it the cautionary title of a plant with "a thin line between poisonous and healing compounds." Its use demands respect and precise dosage, often reserved for experienced practitioners of traditional medicine.

External Look
Drimia indica is easily recognizable by its characteristic bulbous structure and overall morphology, as described below: Habit: It is a perennial, bulbous geophyte, meaning it survives unfavorable conditions by means of an underground storage organ (the bulb). Bulb: The main feature is the bulb, which is tunicated (layered), typically white, globose (spherical), and can measure between 2.5 to 4 cm across. In some African species, the bulb can be much larger, up to 30 cm in diameter, and may be reddish-brown. The bulbs are usually found just below the soil surface. Leaves: The leaves are radical (arising directly from the rootstock/bulb), thick, linear, and canaliculated (grooved). They are acute at the tip, measuring about 10-15 cm long and 0.5-1 cm wide. In many species, the leaves are often dry or absent when the plant flowers. Flower Stalk (Scape): The flowers are borne on a stiff, single stalk called a scape, which is erect and leafless. Initially, the scape is 15-30 cm long, but it can elongate considerably during fruiting, reaching up to 40-60 cm in length. Flowers: The flowers are small, drooping, and typically dull green in color, arranged loosely in a spike-like inflorescence called a raceme. They are 3-merous, with six perianth lobes (tepals) in two whorls. Fruit and Seeds: The fruit is a capsule, about 1 cm across, which is deeply 3-lobed and opens by three valves (loculicidal). Inside, the seeds are numerous, flat, orbicular (circular), and black, measuring about 0.5 cm across.
Healing Properties
The healing properties of Drimia indica are primarily attributed to its high content of cardiac glycosides and other phytochemicals, giving it a powerful, multi-systemic action. Cardiac Stimulant: This is one of its most famous properties, as it acts similarly to Digitalis, stimulating and strengthening weakened cardiac muscles and regulating irregular heartbeats. This makes it a valuable herb for treating cardiac edema (fluid retention due to heart failure). Respiratory Efficacy (Expectorant): The bulb, even in small doses, is a potent expectorant. It helps in expelling excessive Kapha dosha (phlegm/mucus) from the respiratory tract, providing relief in conditions like chronic bronchitis, asthma, cough, and whooping cough. Diuretic: It possesses strong diuretic properties, increasing urine output by stimulating the renal cells and improving blood flow to the kidneys. This action is beneficial for treating dropsy (edema) and chronic renal disorders. Anti-Inflammatory and Analgesic: Scientific studies have shown that the alcoholic extracts of the plant part possess significant anti-inflammatory effects. The fresh tubers are traditionally used as a poultice to reduce swelling, sprains, and joint pains. Anticancer/Antitumor Activity: The herb has demonstrated potent in vivo antitumor activity, particularly against the growth of ascites tumors and mouse mammary carcinoma. The alcoholic extracts are noted for their activity against human epidermoid carcinoma of the nasopharynx. Antimicrobial and Antifungal: The plant exhibits significant antimicrobial and antifungal properties, making it useful in treating various microbial infections, including skin ailments like eczema and carbuncles. Other Properties: It is also classified as a deobstruent (clearing obstructions), emmenagogue (stimulating menstrual flow, useful in dysmenorrhea), and a powerful anthelmintic (worm killer, hence the Sanskrit name Krimighna).
Advantages
The key advantages of using Drimia indica as a medicinal herb lie in its multifaceted actions and availability within traditional medical frameworks: Effective Cardiovascular Action: Its primary advantage is its digitalis-like effect, providing a natural remedy for regulating heart function, which is critical in managing various cardiac ailments. Rapid Expectorant Relief: As an expectorant and bronchodilator, it offers immediate relief in severe respiratory conditions like asthma and persistent coughs by helping to clear the airways. Topical Anti-inflammatory Use: The raw bulb is easily processed into a paste or poultice, providing a readily available local treatment for musculoskeletal issues such as sprains, joint pain, and swellings, especially in rural settings where it is gathered from the wild. Traditional Validation: Its extensive and long-standing use in established systems like Ayurveda and Sidha provides a vast body of knowledge regarding its preparation, dosage, and indications, making it a trusted resource for local healers (vaidyas). Wide-ranging Utility: From treating intestinal worms and skin diseases to its experimental potential against cancer, the herb displays a broad spectrum of utility, making it a versatile component of traditional materia medica.
Uses
The bulb and other parts of Drimia indica are utilized across human and veterinary medicine for various conditions: In Human Medicine: Respiratory Disorders: Used for chronic bronchitis, bronchial asthma, cough, and whooping cough (as an expectorant and bronchodilator). Cardiac Conditions: Employed as a cardiac stimulant for irregular heartbeats and weakened heart muscles, often indicated in cardiac edema. Gastrointestinal Health: In small, controlled doses, the nauseous bitter young bulbous roots act as an emetic (inducing vomiting) and cathartic (inducing bowel movements), used for indigestion and constipation. Urinary Issues: The cold infusion is used in cases of difficulty in micturition (dysuria) due to its diuretic action. Gynecological Disorders: The decoction of the rhizome is given to treat dysmenorrhea (painful menstruation) and amenorrhea (absence of menstruation), owing to its emmenagogue property. External Applications: Swelling and Pain: Fresh tubers are ground into a paste and used as a poultice for sprains, joint pains, and general swelling. Corns: A paste of the bulb, warmed along with jaggery, is applied topically to remove corns. Stomachache: The leaves are heated and tied externally over the stomach to relieve stomachache. Antiparasitic: The plant is used to kill intestinal worms (Krimighna). Cautionary and Veterinary Uses: Abortifacient: Bulb paste is traditionally given for abortion, a use that is highly dangerous and toxic. Veterinary Medicine: Fresh bulb is used for curing stomach pain in cattle (cows and buffaloes). A paste of the tuber mixed with cow urine is applied locally on eczema, carbuncles, wounds, and tumors.
Using way
The usage of Drimia indica is strictly controlled due to its toxicity, requiring precise preparation and very small dosages. The Bulb (tuber or rhizome) is the main part used. Application Method Condition Preparation and Dosage Powder (Internal) Systemic conditions, cardiac stimulant Powdered dry bulb: 150 to 200 mg per dose. Tincture/Syrup (Internal) Cough, asthma, respiratory disorders Syrup/Tincture: 5 to 60 drops (depending on concentration and age) in small doses. Cold Infusion (Internal) Difficulty in micturition (Dysuria) Cold infusion: 40-60 ml per dose. Decoction (Internal) Dysmenorrhea Decoction of the rhizome: 30-40 ml per dose. Juice (Internal/External) Rhinitis, Cough Juice extracted from the heated rhizome: 15-20 ml for internal use. Poultice/Paste (External) Sprain, Joint Pains, Swelling, Corns Fresh tubers are ground into a paste, sometimes warmed with jaggery, and applied directly to the affected area. Leaves are heated and tied on the stomach for stomachache. Export to Sheets Important Note on Toxicity: The plant is poisonous. Large doses are emetic and cathartic. Excessive doses act as a narcotic acrid poison, causing cardiac depression, nausea, and in severe cases, slow, painful, and bloody urination. The use of the bulb, especially for sensitive purposes like abortion, is extremely dangerous and must be avoided outside of professional medical guidance.
Conclusion
Drimia indica, known locally as Ban Pyaaj in Nepal and broadly as the Indian Squill, stands out as a powerful and paradoxical medicinal plant. While it is a valued cornerstone in traditional medicine systems like Ayurveda for its cardiotonic, expectorant, and diuretic effects, its potency is inseparable from its inherent toxicity. Historically, the bulb has been integral to treating a spectrum of ailments, from chronic coughs and cardiac irregularities to topical swelling and joint pains. Scientific research continues to validate many of its traditional uses, confirming its significant anthelmintic, anti-inflammatory, and even anticancer potential due to its unique composition of cardiac glycosides. As a plant gathered from the wild across its distribution, including the varied habitats of Nepal, its preservation and safe, standardized utilization are paramount. In essence, Drimia indica is a potent natural resource that embodies the principle that in medicine, the difference between a remedy and a poison is often nothing more than the correct dosage.
