Solanum tuberosum, commonly called potato, is a tuberous perennial crop, a member of the nightshade family. The potato was a staple food for the Inca Empire in the Andes, and was introduced to Europe by the Spanish in the second half of the 16th century. The spread into Europe and the lower altitudes lead to other species of potatoes being developed. Today potatoes are cultivated throughout the world. The potato contains abundant starch, vitamin B6 and C. It is popular not only as a food, but also as a skin care ingredient. Mashed potato mixed with flour and honey is traditionally used as a face pack. It is used on sunburn skin for the soothing effect and the high levels of vitamin C provides skin brightening and anti-oxidant effect. There have not been many scientific studies on the relationship between skin care and the potato, however, many examples of using potato on skin suggest it may have potential as a cosmetic ingredient. Potato has been known to work well to treat sunburns. It is excellent for drawing out the heat with very high content of water (over 80%). There are some home care remedies. Slice cold potato and place it on the affected areas. Leave them on for about 20 minutes and remove. You can also dab potato juice on the spot. Doing so gives you a cooling sensation and even diminishes your suntan.
