But more people solve the current problems by finding some remedies, such as taking vitamin C to prevent colds and using ginger to treat hair loss.
Are these so-called "ancestral remedies" really useful today?
1. Can vitamin C supplementation really prevent colds? The answer is no.
① Cold is a common acute upper respiratory infection in clinic, which is mostly caused by common respiratory virus infections such as influenza virus, parainfluenza virus and respiratory syncytial virus.
Cold can be divided into common cold and influenza.
Cold is a self-limiting disease. The common cold can heal itself, but the flu should be treated promptly. If not treated in time, you may lose your life.
② Taking vitamin C in a proper amount can improve human immunity and make the human body have a stress reaction when the virus invades, but the human body's own defense system is also very strong, and it can also produce antibodies against the virus. Therefore, the prevention and treatment of colds with vitamin C has not been proved in medicine.
Moreover, taking large doses of vitamin C can cause digestive system diseases such as nausea, vomiting, abdominal pain and diarrhea, as well as rash and urinary calculi, and even cause side effects such as intravascular hemolysis or coagulation and deep vein thrombosis in severe cases.
Not worth the candle!
To sum up, vitamin C is beneficial to human body, but it is not omnipotent.
Never eat casually. As long as you reduce your activities, pay attention to rest, drink more hot water, go to public places as little as possible, and be careful not to have other complications when you have a common cold. Generally, you can heal yourself in a week or so. If it is the flu, it is recommended to see a doctor.
Second, some people think that ginger can treat hair loss and even regenerate hair. Is this correct? The answer is also no.
Causes of hair loss: heredity, aging, chemotherapy, excessive pressure and so on.
The most common pathological alopecia is alopecia caused by androgen, which can occur in both men and women.
Due to the influence of hormone level, the growth period of hair follicle will be shortened, the density and volume of hair follicle will also be reduced, and finally the hair follicle will fall off and shrink. There is alopecia areata.
Ginger can treat alopecia according to different conditions. The main medicinal components of ginger are gingerol and gingerol, which can promote blood circulation. So it has a certain curative effect on alopecia areata.
However, studies have shown that gingerol and gingerol can inhibit cell proliferation, promote cell apoptosis, prolong the resting period of hair and make it grow more slowly.
People with hair loss have thin scalp and most hair follicles atrophy and die.
Therefore, rubbing ginger has no effect, and if the rubbing force is too great to damage the scalp, it will also promote the aging of hair follicles, thus aggravating hair loss.
For some people with sensitive scalp, it may even cause local inflammation, itching, erythema and other adverse reactions.
To sum up, ginger can only treat alopecia areata, but it has no effect on alopecia caused by different reasons, and even accelerates alopecia and produces some adverse reactions. Therefore, if you find a lot of hair loss, you should seek medical advice in time, use some drugs, and add food supplements and conditioning to improve the symptoms of hair loss.
