Herbal Angelica, A Promising Anti-Colorectal Cancer in Vivo

By Kyle J. Norton

Colorectum including the large intestine and the rectum is the second part of the digestive system involved in the absorption of water from the small bowel contents and breaks down certain materials in the feces into substances of which some of them to be reabsorbed and reused by the body.

The colon also is known as the large bowel or large intestine, formed parts of the digestive system in our body.

The colon consists of four parts: descending colon, ascending colon, transverse colon, and sigmoid colon.

The main functions of the colon are to reabsorb fluids and process waste products from the body and prepare for its elimination.

Colorectal cancer is a medical condition caused by irregular cell growth in the tissue of the colon or rectum.

Most cases of colorectal cancer start in the cells on the surface of the inner lining in the colon and rectum, before penetrating into deeper layers to form a tumor through proliferation.

Colorectal cancer is a relatively very slow-growing cancer that progresses in a predictable way.

According to the statistics provided by the American Cancer Society, excluding skin cancers, colorectal cancer is the third most common cancer diagnosed in both men and women in the United States.

In 2019, approximately 101,420 new cases of colon cancer and 44,180 new cases of rectal cancer will be diagnosed in the US.

The 5-year survival rate of colorectal cancer diagnosed at the localized stage is 90%. Sadly, only 39% of patients are diagnosed at this early stage.

Most common types of colorectal cancer classified depending on the primary originated cells are
* Adenocarcinomas
Most bowel cancers are adenocarcinomas, originated in epithelium tissues, including the surface layer of skin, glands and their tissues that line the cavities and organs of the body.

* Squamous cell cancers
Squamous cells are the skin-like cells that make up the bowel lining together with the gland cells. Squamous cell cancers are rare with a risk of 25 per 100000 population.

On finding a natural ingredient for the prevention and treatment of cancers, scientists examined the chemopreventive effect of the supercritical extracts from Angelica sinensis (SFE-AS) on induced colorectal carcinoma in mice.

Angelica or Dang Qui is a herb of Genus Angelica from the family Apiaceae, indigenous to China.

The herb has been used as a Queen herb in traditional Chinese medicine antispasmodic and vasodilatory agent, and to balance the hormones in women for a normal menstrual cycle and menstruation and strengthen heart, spleen, kidneys, and liver for both men and women, etc. In other words, it is used to treat gynecological ailments, fatigue, mild anemia, and high blood pressure. It has analgesic, anti-inflammatory, etc.

According to the results of selected male colorectal carcinoma mice that were subcutaneously injected with single dose of azoxymethane (AOM, 10 mg x kg(-1) body weight) then one week later, given 2% dextran sodium sulfate (DSS) in drinking water for 7 days to induce colorectal carcinoma, following by oral administration of supercritical extracts from Angelica sinensis at 15, 30, 60 mg x kg(-1) until the 17th week,

* The Tumor-bearing quantity and tumor-bearing volume of the SFE-AS group were lower than that of the AOM/DSS model control group.

* The SFE-AS group also showed a significant reduction of oxidative stress in the AOM/DSS-induced mouse colorectal carcinoma model associated with inflammation.

In other words, the application of Angelica sinensis at 15, 30, 60 mg x kg(-1) and strong inhibitory activity against 2% dextran sodium sulfate (DSS)  induced colorectal carcinoma,

Based on the evidence, researchers said, "SFE-AS showed an intervention effect in the incidence and development of AOM/DSS-induced mouse colorectal carcinoma associated with inflammation, and could be further used in chemo-preventive studies on human colorectal carcinoma".

Taken altogether, Herbal Angelica may be considered an anti colorectal cancer herbal remedy, pending to the confirmation of the larger sample size and multicenter human study.
