All the five parts of the plant (that is the PANCHANG) - leaves, flowers, stems, roots, and fruits are used as medicines in the traditional healthcare systems. In India, different parts of the plant have been in popular use for treating various ailments since long. Recent researches show that the extract of this plant can be used for checking child birth. Some authors have reported that this herb can replace contraceptive pills if researches are done properly.

According to different researches done so far, Mimosa Tenuiflora bark is used to relax the mind, and relieve depression, mental distress, irritability, severe palpitations, and amnesia. It is a mood enhancer and improves circulation of the blood. Some believe Mimosa can reduce the onset of baldness. Due to its ability to promote healthy cell growth, Tepezcohuite is used in shampoos, creams, capsules, and soaps. In Ayurvedic and Unani medicine, Mimosa pudica root is used to treat bilious fevers, piles, jaundice, leprosy, dysentery, vaginal and uterine complaints, inflammations, burning sensation, fatigue, asthma, leucoderma, and blood diseases. In Western medicine, Mimosa root is used for treating insomnia, irritability, premenstrual syndrome (PMS), menorrhagia, hemorrhoids, skin wounds, and diarrhea. It is also used to treat whooping cough and fevers in children, and there is some evidence to suggest that Mimosa is effective in relieving the symptoms of rheumatoid arthritis. All parts of the Mimosa plant are reportedly toxic if taken directly. Its consumption is not recommended to pregnant or nursing ladies. Due to these reports, it seams to be best to consult a physician before using Mimosa internally. Researches regarding safety in young children or those with severe liver or kidney disease have not been found.

Common name: Amaryllis Lily
Botanical name: Hippeastrum hybrid Family: Amaryllidaceae (Nargis family)
________________________________________
Hippeastrum is a genus of about 70-75 species and 600+ hybrids and cultivars of bulbous plants in the family Amaryllidaceae, native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean. Some species are grown for their large showy flowers. These plants are popularly but erroneously known as Amaryllis, which is an African genus, in the same family. "Hippeastrum" is Latin for "horseman's star" (also known today as "knight's star") and was chosen in 1837 by the Honorable Reverend William Herbert, Dean of Manchester. No one is entirely sure why he picked this name although buds on the verge of opening do look something like a horse's ear and clearly the blossoms do resemble six-pointed stars. Colors include red, rose, pink, white, orange, yellow and pale green with variations on these including different colored stripes and edges on the petals. Some flowers have uniform colors or patterns on all six petals while others have more pronounced colors on the upper petals than on the lower ones.

The plant lectins derived from Galanthus nivalis (Snowdrop) (GNA) and Hippeastrum hybrid (Amaryllis)(HHA) selectively inhibited a wide variety of human immunodeficiency virus type 1 (HIV-1) and HIV-2 strains and clinical (CXCR4- and CCR5-using) isolates in different cell types. They also efficiently inhibited infection of T lymphocytes by a variety of mutant virus strains. GNA and HHA markedly prevented syncytium formation between persistently infected HUT-78/HIV cells and uninfected T lymphocytes. The plant lectins did not measurably affect the antiviral activity of other clinically approved anti-HIV drugs used in the clinic when combined with these drugs. Short exposure of the lectins to cell-free virus particles or persistently HIV-infected HUT-78 cells markedly decreased HIV infectivity and increased the protective (microbicidal) activity of the plant lectins. Flow cytometric analysis and monoclonal antibody binding studies and a PCR-based assay revealed that GNA and HHA do not interfere with CD4, CXCR4, CCR5, and DC-SIGN and do not specifically bind with the membrane of uninfected cells. Instead, GNA and HHA likely interrupt the virus entry process by interfering with the virus envelope glycoprotein. HHA and GNA are odorless, colorless, and tasteless, and they are not cytotoxic, antimetabolically active, or mitogenic to human primary T lymphocytes at concentrations that exceed their antivirally active concentrations by 2 to 3 orders of magnitude. GNA and HHA proved stable at high temperature (50°C) and low pH (5.0) for prolonged time periods and can be easily formulated in gel preparations for microbicidal use; they did not agglutinate human erythrocytes and were not toxic to mice when administered intravenously.

Gymnema Sylvestre - Destroyer of Diabetes




Family - Asclepiadaceae.
Gurmar in Hindi Literally means - "Destroyer of Sugar".
it known to have a good effect for curbing of diabetes by blocking sugar binding sites and hence not allowing the sugar molecules to accumulate in the body.
The hypoglycemic extract of Gymnema sylvestris brings about blood glucose homeostasis, which in turn prevents increased glycosylation of proteins thus reversing the onset of changes leading to micro and macroangiopathy. Control of Diabetes mellitus and the associated complications are mediated through the revival or regeneration of the insulin, producing beta-cells in the islets of langerhans. The glucose-like molecules in Gurmar known as the gymnemic acid fills the receptor locations in the absorptive external layers of the intestine, thereby preventing the intestine from absorbing the sugar molecules. Due to the change in the absorption level of sugar, there is a consequent change in the blood sugar level.
It is useful in Obesity also.

Berginea ciliata





Family - Saxifragaceae.
Found in the regions of Himalayas, between the altitudes ranging from 900 and 3000m. The rhizome is a well known Indian drug, mentioned by the name PASANADHEDA or Stonebreaker. It was believed to break the rock, in which it lived. It was used to dissolve gravel or stone in the bladder and act as a diuretic.
In higher doses it is cardio-toxic, shows anti-diuretic action, and has depressant action on the central nervous system.
