I've always loved lemons and especially as a child my mother would make lemon meringue pie. We still make this from time to time as it's a delicious treat.
In Greece where I lived for many years, lemons were plentiful and I remember my delight in seeing my first lemon tree, This was growing on a street in Athens. The councils grew bitter orange trees as decoration (their scent in Spring fragrant and the blossom beautiful. Some people knew how to graft them to make lemons instead. Amazing.
The health benefits of lemon include treatment of indigestion, constipation, dental problems, throat infections, fever, internal bleeding, rheumatism, burns, obesity, respiratory disorders, cholera, and high blood pressure, while also benefiting your hair and skin. Known for its therapeutic property since generations, lemon helps strengthen your immune system, cleanse your stomach, and is considered a blood purifier.
Lemon juice, especially, has several health benefits associated with it. It is well known as a useful treatment for kidney stones, reducing strokes, and lowering body temperature. As a refreshing drink, lemonade helps you stay calm and cool.
According to the website Organicfacts.net:
"The health benefits of lemon are due to its many nourishing elements like vitamin C, vitamin B6, vitamin A, vitamin E, folate, niacin, thiamin, riboflavin, pantothenic acid, copper, calcium, iron, magnesium, potassium, zinc, phosphorus, and protein. It is a fruit that contains flavonoids, which are composites that contain antioxidant and cancer-fighting properties. It helps prevent diabetes, constipation, high blood pressure, fever, indigestion, as well as improve the skin, hair, and teeth. Studies conducted at the American Urological Association highlight the fact that lemonade or lemon juice can eliminate the occurrence of kidney stones by forming urinary citrate, which prevents the formation of crystals."
I believe every word as I've used lemons in all kinds of ways and found them to be beneficial. My favourite is one I use every day and have done for decades: Squeeze half a lemon into a cup, add about 1/4 of a teaspoon of ginger, about the same of brown sugar then add a little warm water, stir and drink before breakfast. Great for the skin and I remain wrinkle free even now and I have a great digestion.
I remember speaking to a lovely journalist (from New Jersey) years ago at a travel convention New York, who said to my amusement that if someone really bothered her, she didn't use expletives, she would so "Aw, Go suck a lemon".
I don't recommend you suck a lemon, but you should try making sure they are in your diet.
