NMRV reducer is a new type of reducer, which can also be called RV reducer. "NMRV" is a collective term, which refers to aluminum housing reducer, and it is customary to call aluminum housing reducer as "NMRV reducer" in the world. The main components are oil seal, oil plug, worm gear box, ball bearing, output shaft, worm gear, worm, output shaft, motor connection plate (flange), output shaft cover, hexagon socket head screw, double key, gasket, etc. One of the NMRV series reducers, BHADE reducers, some have a single flange input, some have a flange output or a double shaft output, etc. Nmrv-nrv worm gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear box is generally used to take a rated motor speed and produce a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems because the nmrv-nrv worm gear reducers is one of the sleekest reduction gearboxes available due to the small diameter of its output gear Super reducer use high quality main material: aluminum, copper, iron material Be popular of its high quality and competitive price and prompt delivery in china and abroad The Basic model: NRV25, NRV30, NRV40, NRV50NRV63NRV75NRV90NRV110NRV130NRV150 NMRV25NMRV30NMRV40NMRV50NMRV63NMRV75NMRV90NMRV110NMRV130NMRV150

Senna Plant Benefits For Health: As stated above, senna possesses medicinal value which can provide various health benefits given below. 1. Senna For Constipation: Being a laxative, senna is effective in relieving constipation. It has been approved by the US FDA as a non prescription drug to treat constipation. Senna stimulates the muscles of the colon to push fecal matter through more quickly. Senna leaf acts on the intestinal walls to cause contractions that lead to bowel movements. It softens stool by enabling the colon to absorb water. It can effectively cure even the most severe cases of constipation. The glycosides in it help transport electrolytes, causing bowel movements within 6 to 12 hours of its intake. Senna can be bought as an over the counter (OTC) medication for adults and children above 2 years of age.  2. Great Colon Cleanser: Senna has been regarded as a â??cleansing herbâ?? due to its laxative effects. Senna leaf is used in traditional Chinese medicine to clear away the heat accumulated in the large intestine, helping the body get rid of the stagnant food accumulated in the stomach. Today, it is widely used in cleansing the colon before colonoscopy and other types of colon surgery. 3. Treatment of Hemorrhoids: Senna has been found to be effective in the treatment of anal lacerations and hemorrhoids as it helps reduce swelling and facilitates quick healing. Moreover, since it promotes soft stools, it helps cause easy defecation in pathological conditions like anal fissure. This is due to the fact that after oral ingestion, the compounds in senna get absorbed into the intestinal tract, resulting in the separation of non-sugar parts in the colon. These non-sugar components increase the peristaltic movements by irritating and stimulating the intestinal tract. In this way, it speeds up the passage of stools through the intestinal tract. 4. Treatment of Intestinal Worms: The laxative properties of senna have been found to be useful in the treatment of worms in the stomach and colon.  Senna Medicinal Plant: Nutritional Value: The nutritional value of this herb has been explained in the table below. As evident from the table, it is devoid of calories and fat but a rich source of vitamin B
SENNA PODS Senna has been used as a traditional medicine by ancient cultures all over the world for millennia. Senna is an Arabian name and 9th century writings describe how it was used extensively by Arabian physicians. According to a rare Egyptian medical papyrus, dating to the 16th century BCE, Senna was prescribed by the physicians for their distinguished patients. In North America, native tribes used the seeds (pods) as a mucilaginous medicine for sore throat. The Cherokees used the bruised root, moistened with water, for dressing sores. They also used it in a tea to cure fevers with black spots and paralysis as symptoms. Senna Pods Uses: Taking senna by mouth is effective for short-term treatment of constipation. Senna is an FDA-approved nonprescription drug for adults and children ages 2 years and older. However, in children ages 3-15 years, mineral oil and a medication called lactulose might be more effective than taking senna. Senna also appears to be effective for treating constipation when used in combination with psyllium or docusate sodium. In elderly people, senna plus psyllium is more effective than lactulose for treating ongoing constipation. Senna plus docusate sodium is effective for treating constipation in the elderly and in people who have undergone anorectal surgery. Taking senna appears to be as effective as lactulose, psyllium, and docusate for relieving constipation in people taking opioids or loperamide. Senna Benefits Constipation The most famous use of this herb is as a laxative and a purgative. It is now known that the laxative effects of Senna are due to anthraquinone glycosides known as sennosides. These compounds stimulate intestinal contractions that lead to the rapid expulsion of waste matter. Senna may also be able to soften the stool by assisting the large intestine to absorb more water and adding bulk to faeces. This allows for bowel movements that are quick and smooth as waste passes through the large intestine. Colon Cleanse Senna is often used to clear the bowel before diagnostic tests such as colonoscopies. Cleansing the colon is believed to improve nutrient uptake and support overall colon health. Anti-Parasitic:Senna also works as an effective vermifuge to destroy parasites and expel worms from the intestinal tract. It works best when combined with other anthelmintic herbs (used in the treatment of roundworm), such as ginger or fennel. These herbs increase regularity and reduce the chance of bowel cramps due to Sennaâ??s strong action. Digestive Health In the case of indigestion, Senna contains natural enzymes that help to restore gastric juice secretions in the stomach. Senna, if used in the proper dosage for certain periods of time, has shown potential in reducing irritability in the intestines by improving overall digestion. Senna also contains the anti-inflammatory compound resveratrol which can help to soothe inflammation in the gastrointestinal tract. Skin Health
