Fengyoujing can help you last longer without ejaculation

Cooling oil has always been a must-have at home or when traveling. It can not only prevent mosquitoes and relieve itching, but also refresh the air and disinfect. It is popular because of its low price, good quality and remarkable effect. In addition, some people used cooling oil to do some unspeakable things on the Internet not long ago, which made cooling oil famous. Many people have also discovered more uses of cooling oil. So, can cooling oil last for a long time without leaking? Today, let's introduce why cooling oil is so magical.

Can the cooling oil help you last longer without ejaculation?

There is no way to cure it with cooling oil. There is no scientific evidence for the claim of prolonged intercourse without ejaculation, so you don't have to blindly believe in and try it. If intercourse is not lasting, it may be premature ejaculation caused by kidney deficiency. You can also take some kidney-tonifying and essence-replenishing medicines for conditioning. Most of them recommend long-term conditioning, because short-term effects may not be very obvious. You should also increase physical exercise on a regular basis to improve your physical fitness.

The key ingredients of cooling oil are menthol, eucalyptus oil, camphor balls, clove pollen, methyl salicylate, etc. Each ingredient fully exerts different effects.

Menthol

Menthol, also known as menthol, comes from the leaves and stems of mint. It is the main component of cooling oil and has a minty aroma. It is very insoluble in water and soluble in ethanol. It is a saturated alcohol that can interact with the cytoplasm of neurons, inhibiting Na influx and producing a local anesthesia effect.

When menthol is applied to the skin, if the concentration is low (<2%) it can selectively stimulate the body's cooling effector, causing a cooling reflex that can cause a cold; but if the concentration is too high it can cause irritation and burning sensations. Menthol will slowly penetrate the skin, causing local long-term hematoma, reflexively causing superficial changes in blood vessels, and achieve the therapeutic effects of regulating blood vessels, such as anti-inflammatory and analgesic.

Menthol can also be used for respiratory treatment. Because menthol can reduce the foam of blood and saponin, it can reduce the foam sputum in the respiratory tract and expand the ventilation channel.

Eucalyptus Oil

Eucalyptus oil is an essential oil metabolized by the oil gland cells of eucalyptus leaves. It has an aroma. Eucalyptus oil has antibacterial and anti-inflammatory effects, and has excellent inhibitory effects on Escherichia coli, Staphylococcus aureus, and Cholera. There is also a folk custom of using eucalyptus leaves to boil water for bathing to prevent eczema.

Eucalyptus oil can improve the respiratory system. Eucalyptus oil has a mild stimulating effect on the nasal and bronchial mucosa, can promote mucus metabolism, and help clear the respiratory tract.

It is worth mentioning that eucalyptus oil can also be used as a freshener, which has a disinfecting and sterilizing effect on the air. Some dental hospitals also use eucalyptus oil as an anti-septic and deodorizing ingredient in oral fresheners.

Mothballs

Camphor balls are obtained by distilling the branches and trunks of camphor trees with water vapor. They are harmful. Taking 0.5 to 1g can cause dizziness, headache and other symptoms. Taking more than 2g for adults can cause death, while children only need 0.75g.

Applying camphor balls to the skin will create a refreshing feeling and have a weak anesthetic effect. In medicine, camphor balls are used as ointments to relieve pain and itching.

Camphor balls have a stimulating effect on the central nervous system, especially on the higher nervous centers, and many of them are effective in the motor area of ​​the cerebral cortex and the spinal cord. Therefore, cooling oil has the effect of relieving fatigue and removing sleepiness.

Methyl salicylate

Methyl salicylate has a partial stimulating effect, which can promote blood flow. When applied externally, it can affect the skin, muscles, nerves and joints in the corresponding position, and has the effects of reducing swelling, inflammation, and pain, as well as relieving itching. It can be used to treat sprains, injuries, back pain, neuralgia and other symptoms.

The ingredients detailed above are all irritating and even harmful. You should not use them independently, but should use them properly under the supervision of a doctor. Although each ingredient is harmful, the cooling oil composed of them still has many uses and the actual effect is also very obvious. However, because the cooling oil is more irritating, you should remember not to learn from the Internet and apply it to certain specific places to avoid causing psychological damage (curiosity harms cats).
