The Potato, botanically known as Solanum tuberosum L., is one of the world's most vital food crops, belonging to the nightshade family, Solanaceae. While primarily recognized for its culinary uses, this plant, particularly its tubers, holds significant traditional medicinal applications globally, including in regions like Nepal, which is rich in medicinal flora.
Herb's Introduction
The herb in question is Solanum tuberosum L., commonly known as the Potato. It's a perennial plant, but typically cultivated as an annual crop worldwide for its starchy tuber, which is a thickened part of the underground stem. Native to the Americas, it has become a staple food in many cultures and is the world's fourth most important food crop, after maize, wheat, and rice. Its importance extends beyond sustenance, as various parts of the plant, especially the tuber and leaves, have been historically utilized in traditional medicine systems like Ayurveda and various folk remedies.

Terminology
Botanical Name: Solanum tuberosum L. Family: Solanaceae (the nightshade family, which also includes tomatoes, eggplant, and peppers). Part Used Medicinally: Primarily the tuber (potato itself), but also the leaves and juice. Ayurvedic Qualities (as per traditional texts, though sometimes debated): Can be considered Durjara (Heavy/Difficult to digest) and Vishtambhi (causes bloating/constipation), but is also Balya (improves strength), and Vrishya (aphrodisiac). Its rich content of iron and folic acid also makes it useful for Pandu (anemia).
Availability
Global: Potatoes are cultivated almost everywhere in the world, from the temperate lowlands to high altitudes, making them highly available and one of the most accessible food and medicinal plants globally. Nepal (Medicinal Plants of Nepal): In Nepal, the potato is a significant food and cash crop. It is widely grown from the southern Terai plains up to the high mountains (as high as 4000 m), where it can even be a staple food. Its widespread cultivation ensures that it is readily available in virtually all parts of Nepal, both for consumption and traditional medicinal uses.
External Look
The potato plant is a herbaceous annual (when cultivated) or perennial plant. Height: Typically grows up to about 1 meter tall. Leaves: They are alternate, pinnately compound, and often slightly hairy. Flowers: The flowers are typically white, pink, red, blue, or purple, with yellow stamens. Fruit: After flowering, the plant produces small green berries, similar to tiny tomatoes, which are highly toxic and not consumed. Tuber (The Potato): This is the most distinctive and useful part. It is an underground storage stem (not a root), known for its irregular, rounded, or oblong shape. The skin colour can vary significantly (yellow, brown, red, purple), as can the flesh (white, yellow, purple). The surface contains "eyes," which are buds from which new plants can grow.
Healing Properties
The therapeutic properties of Solanum tuberosum stem from its rich phytochemical profile, including starches, vitamins, minerals, and various bioactive compounds like phenolic acids (e.g., chlorogenic acid), flavonoids, and in small, safe quantities, certain alkaloids. Key healing properties include: Anti-ulcer/Anti-acid: The raw juice of the tuber is traditionally used due to its anti-acid and healing properties, which help bring relief from pain and acidity associated with gastritis and peptic ulcers. The presence of small quantities of atropine-like alkaloids is believed to reduce digestive secretions. Anti-inflammatory and Soothing: Raw or boiled potato poultices are used externally to soothe burns, scalds, skin rashes, and inflammations. Internally, the high content of minerals and organic salts is noted for its anti-inflammatory action, beneficial in conditions like arthritis and rheumatism. Antioxidant: Potatoes, especially colored varieties, are rich in phenolic compounds and Vitamin C, which provide strong antioxidant protection against cell damage and diseases like atherosclerosis. Digestive Aid: The fiber content in boiled/steamed potatoes helps promote soft stools, making it an effective natural remedy for constipation and for preventing hemorrhoids.
Advantages
Nutritional Powerhouse: Beyond medicinal uses, it is a significant source of Potassium (which helps lower blood pressure and eliminate uric acid, beneficial for rheumatism and gout), Vitamin C, Vitamin B6, and essential minerals like Iron and Folic acid (useful for anemia). Wound Healing: The juice or paste is applied to cuts and wounds to help stop bleeding and promote tissue regeneration and wound-healing processes. Skin and Eye Care: Raw potato slices are a folk remedy for reducing dark circles and swelling around the eyes due to their soothing and de-congesting properties. Accessibility and Affordability: Being a globally cultivated staple, it is easily available and very affordable compared to many other herbs, making it a accessible home remedy.
Uses
The Potato is used extensively in both food and traditional medicine: Use Category Application Internal Medicinal Uses Raw juice for peptic ulcers, gastritis, and high acidity. Boiled or steamed for constipation, hemorrhoids, and as a potassium-rich diet for hypertension. Leaf extract is used as an antispasmodic in cough. External Medicinal Uses Raw slices/poultice for burns, scalds, skin rashes, swollen gums, rheumatic joints, and to reduce swelling. Applied to stop bleeding on cuts. Culinary Uses Used as a staple food globally. Consumed as a vegetable, baked, boiled, fried, and processed into products like starch, flour, and alcohol. Animal Health (In Nepal) Powder of the underground part is sometimes given to cattle as a tonic or against diarrhea and intestinal worms. Export to Sheets
Using Way
The methods for using the Potato vary depending on the ailment: For Peptic Ulcers and High Acidity: Raw potato juice is the typical preparation. The juice of one large raw potato is extracted (e.g., using a juicer or grating and squeezing) and consumed, usually in moderation (not more than the juice of one large potato per day to avoid potential toxicity from excess alkaloids in some varieties). For Rheumatism, Swellings, and Skin Rashes: A poultice is often made. This can be prepared by boiling potatoes in water and applying the warm mash (as hot as can be tolerated) to the affected area, or by applying a paste of uncooked, grated potato for soothing and anti-irritating effects. For Cough: A traditional method involves using an extract of the leaves as an antispasmodic. Note: This should be approached with caution as the leaves, like the fruit, contain higher concentrations of toxic alkaloids than the tuber. For Cuts and Bleeding: The raw juice or paste of the tuber is applied directly to the wound to help stop the bleeding and promote healing.
Conclusion
The Potato (Solanum tuberosum L.) is a herb of extraordinary dual importance, serving as a global dietary cornerstone and a versatile subject in traditional medicine, including in the context of the Medicinal Plants of Nepal. Its readily available and affordable nature makes it a valuable, accessible home remedy. Its medicinal applications, particularly the raw juice for stomach disorders like peptic ulcers and its use in external anti-inflammatory poultices for rheumatism and skin irritations, are supported by its rich content of starches, minerals (especially potassium), and bioactive antioxidants. However, as with any plant in the Solanaceae family, a clear distinction must be made between the safe edible tuber and the potentially toxic leaves and fruit, and caution should be exercised regarding dosage, especially with raw preparations. It truly stands as a testament to how essential food crops can also harbor profound therapeutic virtues.
