5 Medicinal benefits of Sugarcane

Sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, typically three to four meters high and about five centimeters in diameter. The stems grow into cane stalk, which when mature constitutes approximately 75% of the entire plant. A mature stalk is typically composed of 11–16% fiber, 12–16% soluble sugars, 2–3% non-sugars, and 63–73% water. A sugarcane crop is sensitive to the climate, soil type, irrigation, fertilizers, insects, disease control, varieties, and the harvest period. The average yield of cane stalk is 60-70 tonnes per hectare per year, however this figure can vary between 30 and 180 tonnes per hectare depending on knowledge and  crop management approach used in sugarcane cultivation. Sugarcane is a cash crop , but it is also used as livestock fodder. [ 6] 1. Sugarcane juice increases vigour and sexual ability. 2. improvement takes place in burning in urine, thirst, cough, fever, indigestion, joint pain et

Investing in penny stocks

Investing in penny stocks The first question is 'To invest or not invest' in penny stocks. This is largely a personal decision that reflects your risk profile. If have the capacity as well as the nature to take greater risks, you could be looking at penny stocks. If your financial position is not very strong, and you have little spare money to invest, it is better that you keep off penny stocks altogether and look at established stocks only. Similarly, even if you have a lot of money to spare but are generally averse to taking risks, it is better that you don’t invest in penny stocks. If you are the kind of person, who likes to take risks in order to increase your returns, and can afford to lose some money if it comes to that, then you could look at penny stocks.

Shocking and Interesting Facts about Stuttering

Shocking and Interesting Facts about Stuttering How do people usually react when they hear someone stutter? They most likely make fun of the stuttering person. And how do people usually perceive someone who stutters? Stupid, dumb, or even good for nothing. A person’s competence or personality is always judged based on how good a speaker he is. That is a sad reality for many people who tend to stutter. Whether you are among the 1 percent of the world’s population that stutters or not, it helps to know and understand the basic facts about this speech condition to put things in a better perspective. This is especially helpful for parents with children who stutter.
