Lemons with a thin skin contain citric acid and a lot of vitamin C. They taste very good, but they are also important remedies for flu caused by viruses and bacteria, for sore throats, bronchitis and many others. If you feel sick, drink a lot of their juice.
A medically more valuable variety has much larger lemons up to two kilograms. It contains hardly any pulp. They are used to make lemonade. The bark of the tree has small warts and bumps and smells very aromatic. Leaves and fruits of this tree are important remedies for fever.
The fruits are not cooked as a remedy, but simply eaten.
The leaves of the tree are boiled in wine for at least 1/2 hour. Put water over and over again. You can also boil them in water, but the sour taste of the wine better releases the healing powers. After cooking, strain the wine through a cloth and drink often throughout the day.
People who respond well to lemon tree remedies often have a very strong sex drive. That is why this tree is called the tree of abstinence in monastery medicine.
