Scientific research gets its that Black cumin oil contains nigellone, which protects guinea pigs from histamine-induced bronchial spasms (perhaps explaining its use to relieve the symptoms of asthma, bronchitis, and coughing).
The presence of an anti-tumor sterol, beta-sitosterol, lends credence to its traditional use to treat abscesses and tumors of the abdomen, eyes, and liver.
Nigella sativa oil has been reported to be effective in treating opioid dependence.
Nigella sativa also has been reported to reduce calculi formation in rats' kidneys.
Thymoquinone and pancreatic cancer treatment
Researchers at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found that thymoquinone, an extract of Nigella sativa seed oil, blocked pancreatic cancer cell growth and killed the cells by enhancing the process of programmed cell death, (apoptosis). While the studies are in the early stages, the findings suggest that thymoquinone could eventually have some use as a preventative strategy in patients who have gone through surgery and chemotherapy or in individuals who are at a high risk of developing cancer.

Aloe vera

Botanical Name : Aloe vera
Kingdom - Plantae
Order - Asparagales
Family - Asphodelaceae
Genus - Aloe
Species - Aloe vera

Different Name as per Country :
In India, Aloe vera is known as Ghrtakumari.
In Pakistan, Aloe vera is known as Quargandal.
In South America, Aloe vera is known as Sabila.
In Thailand, Aloe vera is known as Crocodile Tail.
In Kerala, Aloe vera is known as Kattar vazha.

Historical uses :
Aloin was the common ingredient in OTC laxative products in the United States prior to 2003, when the FDA ruled that aloin was a class III ingredient, therefore banning its use. It should be noted that processed aloe that contains aloin is used primarily as a laxative, whereas processed Aloe vera juice that does not contain significant amounts of aloin is used as a digestive healer. Manufacturers commonly remove aloin in processing due to the FDA ruling.
Culinary uses :
Aloe is also used as a foodstuff. Some molecular gastronomists have begun to take advantage of its gelling properties. Perhaps most notably among these is Chef Quique Dacosta's "Oysters Guggenheim," created at El Poblet in Spain.
Biologically active compounds
Aloe vera leaves contain a range of biologically active compounds. The best studied being acetylated mannans, polymannans, C-glycosides, anthrones and anthroquinones and various lectins.

Medicinal uses
Scientific evidence for the cosmetic and therapeutic effectiveness of Aloe vera is limited and when present is typically contradictory. Despite this, the cosmetic and alternative medicine industries regularly make claims regarding the soothing, moisturising and healing properties of Aloe vera, especially via Internet advertising. Aloe vera gel is used as an ingredient in commercially available lotion, yogurt, beverages and some desserts. Aloe vera juice is used for consumption and relief of digestive issues such as heartburn and irritable bowel syndrome. It is common practice for cosmetic companies to add sap or other derivatives from Aloe vera to products such as makeup, tissues, moisturizers, soaps, sunscreens, incense, razors and shampoos. Other uses for extracts of Aloe vera include the dilution of semen for the artificial fertilization of sheep, use as fresh food preservative, and use in water conservation in small farms.
A more recent review (2007) concludes that the cumulative evidence supports the use of Aloe vera for the healing of first to second degree burns. In addition to topical use in wound or burn healing, internal intake of Aloe vera has been linked with improved blood glucose levels in diabetics, and with lower blood lipids in hyperlipidaemic patients, but also with acute hepatitis (liver disease). In other diseases, preliminary studies have suggested oral Aloe vera gel may reduce symptoms and inflammation in patients with ulcerative colitis. Compounds extracted from Aloe vera have been used as an immune stimulant that aids in fighting cancers in cats and dogs; however, this treatment has not been scientifically tested in humans. The injection of Aloe vera extracts to treat cancer has resulted in the deaths of several patients.
Topical application of Aloe vera may be effective for genital herpes and psoriasis. However, it is not effective for the prevention of radiation-induced injuries. Although anecdotally useful, it has not been proven to offer protection from sunburn or suntan. In a double-blind clinical trial the group using an Aloe vera containing dentifrice and the group using a fluoridated dentifrice both demonstrated a statistically significant reduction of gingivitis and plaque.
Aloe vera extracts have antibacterial and antifungal activities. Aloe vera extracts have been shown to inhibit the growth of fungi that cause tinea, however, evidence for control beneath human skin remains to be established. For its anti-fungal properties, Aloe vera is used as a fish tank water conditioner. For bacteria, inner-leaf gel from Aloe vera was shown to inhibit growth of Streptococcus and Shigella species in vitro. In contrast, Aloe vera extracts failed to show antibiotic properties against Xanthomonas species.
