Health benefits of potatoes (Solanum tuberosum)
Potatoes from America
Potatoes (Solanum tuberosum L) constitute a very old food, used by people in America, before Christopher Columbus discovered it. It seems that old Incas already consumed it habitually.
From America it was carried to Europe, although it took quite a long period to be adopted as a food, since the plant was toxic and it was thought that the consumption of the potatoes could cause illnesses equally. It didn’t generalize until the XVII century, because the shortage of foods that reigned during this time forced to make use of it.
Potato plant is toxic
Indeed the potato plant is toxic. It contains an alkaloid named solanine (C45H73NO15) that appears in all the external parts of the plant (leaves, stems, flowers and fruits) and also in the tender buds of the tubers when they germinate.

The ingestion of the plant produces gastrointestinal, hepatic and heart damages that can be, in case that the ingestion is high, deathly. (More information in” Toxicity of potato”)
MEDICINAL PROPERTIES OF POTATOES
Potato, a soothing food for skin problems
It is one the vegetables that contains more starch, a product with emollient properties, soothing the skin. This property makes the potato or its juice can be used in external use to combat the stomach problems, since it has antacid properties.(Just peel several potatoes and mash them. Filter the juice with a cloth and take half cup twice a day) The same preparation is considered appropriate to combat the hepatic problems.
Equally, in external use, the same liquid can be applied as an ointment on the areas of the aching body to combat pain, to reduce the inflammations or to heal the wounds, being interesting in cases of blows, black eyes, twists, bladders, burns, included sunburns, frostbites, scars, etc. Also apply the slices of peeled potato on the part of the affected body. A poultice made with raw grated potato can be used for treating hematomas.

is toxic, the same as the flowers and the leaves.
Very common homemade remedies are the placement of slices of peeled fresh potato on a solar burn, on the tired or aching eyes, conjunctivitis, tired eyes, swollen eyes, cataracts, styes or on chilblains. In a same way this treatment can be applied on the aching articulations affected by rheumatism in order to calm the pain.(arthritis or osteoarthritis) Potatoes can also be used to make skin masks to treat acne.
The plant that presents a bigger content in starch is the exotic durian (Durio zibethinus L), a tree of the bombaceae family that is cultivated in Indonesia and Malaysia with a very distinctive fruit considering its size that can achieve 25 cm and whose roasted seeds are eaten as if they were chestnuts. Other plants with a great richness are tapioca (Manihot esculenta), rice (Oryza sativa L) or mango (Mangifera L. indica) or chestnut (Castanea sativa)
Given the possible toxicity of the raw potato, the homemade elaboration of medicinal products with raw potato is dissuaded, especially those of internal use.
