In the laboratory, cell samples need to be placed in liquid nitrogen for cryogenic storage. However, some samples must not only be cryopreserved, but also stored in the gas phase without contact with liquid nitrogen. The former can be solved with a conventional liquid nitrogen tank, and the latter can also be solved with a gas-phase liquid nitrogen tank. However, the capacity of gas phase tanks is relatively large, above 350 liters, and the samples that laboratories need to store in gas phase are not always large. When the quantity is small, using gas phase tanks to store them is really overkill. So how to preserve these samples? There is a small gas-liquid nitrogen tank, you can also call it a small gas-liquid tank! It is also specially used for gas phase storage of stem cells, embryos, semen and other biological samples. It has moderate capacity, low liquid nitrogen loss, easy operation, and is more suitable for laboratory gas phase storage of small quantities of samples. Its gas-phase preservation principle is very simple. It is based on the characteristics of liquid nitrogen having a boiling point of -196.56�°C under normal pressure and the natural formation of nitrogen. The area of the small gas-liquid phase liquid nitrogen tank is divided into two, liquid nitrogen is placed at the bottom, and the sample is frozen. The rack is suspended above the liquid nitrogen, and with the help of the natural volatilization of the liquid nitrogen, a low-temperature environment is formed in the container. At this point, is there a familiar and unfamiliar feeling? That's right, the small gas-liquid phase tank is a smaller version of the YDD series gas-phase liquid nitrogen tank. Except for the difference in material and capacity, the rest of the characteristics are the same. For example: compatible with gas-liquid phase dual-mode storage, intelligent management system, etc.; therefore, the principles between the two are also interoperable! In short, the small gas-liquid phase tank makes up for the YDD series's demand for small-volume cell storage in terms of capacity. It is a lightweight and energy-saving gas-phase storage liquid nitrogen container specially designed for gas-phase storage of small-capacity cell samples.
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

Mace Botanical: Myristica fragrans Family: N.O. Myristicaceae Hindi Name: Mace - Javitri General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia. Geographical Sources The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed. Varieties -> Whole nutmegs are grouped under three broad quality classifications: 1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes. 2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%. 3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%. Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter. Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
Castor meal is also variously called castor meal, castor residue, castor extract & de-oiled castor cake Castor meal - the residue obtained from castor cake by the solvent extraction process - is one of the most versatile natural manures. It is truly organic manure which enhances the fertility of the soil without causing any damage or decay. It is enriched with the three big elements vital and conducive to the proper growth of crops - Nitrogen, Phosphorus and Potassium. It also has traces of nutrients like Manganese, Zinc and Copper, thus making it a balanced fertilizer. Moreover, it helps to neutralize the detrimental effects of chemical fertilizers. Apart from their contribution to Nutrients, they have a number of benefits in agriculture, which none of the synthetic fertilizers or pesticides can offer. They bring in the wonderful molecules that nature has designed to help the plants flourish naturally. They provide slow and steady nourishment, stimulation, protection from soil nematodes and insects; improve yields, and quality of product like taste, flavour, amino acid composition etc. The pressed cake obtained after the expression of castor bean. The solvent extracted cake, although rich in protein cannot be used as cattle fodder because of its toxicity. However, it can be used as a fertilizer. The protein content of castor seed meal varies from 21-48% depending upon the extent of decortications. It has an ideal amino acid profile with moderately high Cystine, mithionine, and isoleucine. But its ant nutritional substances, ricin, ricine and an allergen restrict its use in poultry feed, even at a very low level of inclusion. Castor Cake is an excellent fertilizer because of high content of N (6.4%), Phosphoric Acid (2.55%) and Potash (1%) and moisture retention. There is negative correlation between the contents of ricinine in castor seeds and oil content (r = -0.76). This content of ricinine in castor seed is determined by Agro climatic conditions. Nutrient content of Castor Cake: Organic matter - 75 - 80 %, Nitrogen - 4.0 - 4.5 %, Phosphorous - 1.5 %, Potassium - 1.25 - 1.5 %. It also contains some micro nutrients viz., Calcium, Magnesium, Sulphur, Iron, Zinc, Manganese, Copper etc. A typical composition of castor residue/meal is as follows: Nitrogen - 4% min. approx. Phosphorous - 1% min. approx. Potassium - 1% min. approx. Moisture - 10 - 12 % max. approx. Oil Content - 0.7% max. approx. Advantages: 1. It provides all the major & minor nutrients necessary for better plant growth. 2. It also helps in increasing the nutrient uptake by plants. 3. It improves the soil fertility and productivity. 4. It is known to protect the plants from nematodes and termites. 5. It improves the yield & quality of the farm produce. 6. It improves the physical, chemical and biological properties of soil
The Cashew tree (Anacardium Occidentale) is a tropical evergreen native to the Americas but is now widely cultivated in Asia and Africa. Cashew in its natural form is a soft, white, meaty kernel contained within the hard shells of kidney shaped, raw cashew nuts. Cashew is consumed all over the world as a snack or used as a food ingredient. Every year, the world eats more than 600,000 metric tons of cashew. And fortunately, it’s a very healthy food. Cashew nuts are among the most nutritious nuts in the world. Cashew Nuts are low in fat, have zero cholesterol, are high in protein, and include a large amount of important vitamins and minerals. Every single cashew nut comes from its own cashew apple, which are grown on cashew trees and thrive in tropical climates. The nuts are then collected, dried, shelled, peeled, graded, and roasted.
Capsicum Oleoresin is prepared by extracting the crushed capsicum (Capsicum Annum Linn) with volatile solvents by percolation method. It contains the pungent principles, capsicin not less that 8 percent. It also contains the red colouring matter called Capsanthin. This product is a powerful irritant and a carminative, which is also used as a counter irritant in lumbago and neuralgia. It can also be used to treat stomach ache that involves poorly functioning stomach muscles and as an antibacterial agents. Extraction of oleoresin capsicum from peppers involves finely ground capsicum, from which capsaicin is extracted in an organic solvent such as ethanol. The solvent is then evaporated, and the remaining wax like resin is the oleoresin capsicum. An emulsifier such as propylene glycol is used to suspend the OC in water, and pressurized to make it aerosol in pepper spray. The high performance liquid chromatography (HPLC) method is used to measure the amount of capsaicin within pepper sprays. Scoville Heat Units (SHU) are used to measure the concentration or "heat" of pepper spray. A synthetic analogue of capsaicin, pelargonic acid vanillylamide (desmethyldihydrocapsaicin), is used in another version of pepper spray known as PAVA spray which is used in the United Kingdom. Another synthetic counterpart of pepper spray, pelargonic acid morpholide, was developed and is widely used in Russia. Its effectiveness compared to natural pepper spray is unclear. Pepper spray typically comes in canisters, which are often small enough to be carried or concealed in a pocket or purse. Pepper spray can also be bought concealed in items such as rings. There are also pepper spray projectiles available, which can be fired from a paintball gun. It has been used for years against demonstrators. Derived from chilli peppers, oleoresin capsicum is the active ingredient in pepper spray and in some topical pain relievers.
Ginger root Botanical name: Zingiber officinale Linn. Family: Zingiberaceae. Ginger oil and oleoresins are the volatile oil derived by steam distillation of ginger and oleoresin. It is obtained by percolating the powdered rhizomes of Ginger, Zingiber officinale with volatile solvents. Ginger contains 1-2 percent of volatile oil, 5-8 percent of pungent acrid oleoresin and starch. Zingiberene is the chief constituent in the oil of ginger. Oil is employed for flavoring all kinds of food products and confectionary and finds limited use in perfumery. Oleoresin, commercially called Gingerin contains pungent principles viz. gingerol and shogaol apart from the volatile oil of ginger and is used as an aromatic, carminative, stomachic and as a stimulant. Oleoresin from ginger is obtained conventionally by extraction of dried powdered ginger with organic solvents like ethyl acetate, ethanol or acetone. Commercial dried ginger yields 3.5-10.0 per cent oleoresin. Ginger oleoresin is a dark brown viscous liquid responsible for the flavour and pungency of the spice. Ginger of commerce or `Adrak` is the dried underground stem or rhizome of the plant, which constitutes one of the five most important major spices of India, standing third or fourth, competing with chillies, depending upon fluctuations in world market prices, world market demand and supply position. Ginger, like cinnamon, clove and pepper, is one of the most important and oldest spices. It consists of the prepared and sun dried rhizomes known in trade as `hands` and `races` which are either with the outer brownish cortical layers (coated or unscraped), or with outer peel or coating partially or completely removed. Ginger requires a warm and humid climate. It is cultivated from sea level to an altitude of 1500 meters, either under heavy rainfall conditions of 150 to 300 cm or under irrigation. The crop can thrive well in sandy or clayey loam or lateritic soils. The composition of dry ginger is given below: Dry Ginger rootMoisture:6.9 % Protein:8.6 % Fat:6.4 % Fiber:5.9 % Carbohydrates:66.5 % Ash:5.7 % Calcium:0.1 % Phosphorous:.15 % Iron:0.011 % Sodium:0.03 % Potassium:1.4 % Vitamin A:175 I.U./100 g Vitamin B1:0.05 mg/100 g Vitamin B2:0.13 mg/100 g Niacin:1.9 mg/100 g Vitamin C:12.0 mg/100 g Calorific value:380 calories/100 g. Ginger Oleoresin is obtained by extraction of powdered dried ginger with suitable solvents like alcohol, acetone etc. Unlike volatile oil, it contains both the volatile oil and the non-volatile pungent principles for which ginger is so highly esteemed. Concentration of the acetone extract under vacuum and on complete removal of even traces of the solvent used, yields the so called oleoresin of ginger. Ginger oleoresin is manufactured on a commercial scale in India and abroad and is in great demand by the various food industries.
Herbal/folk tradition - Onion has an ancient reputation as a curative agent, highly extolled by the schools of Galen and Hippocrates. It is high in vitamins A, B and C and shares many of the properties of garlic, to which it is closely related. Raw onion helps keep colds and infections at bay, promotes strong bones and a good blood supply to all tissues. It acts as an effective blood cleanser that, along with the sulfur it contains, helps to keep the skin clear and in good condition. It has a sound reputation for correcting glandular imbalance and weight problems; it also improves lymphatic drainage, which is often responsible for edema and puffiness. It has long been used as a home simple for a wide range of conditions. Aromatherapy/home use-- Non, due to its offensive smell. Other uses -- used in some pharmaceutical preparations for colds, coughs. The oil is used extensively in most major food categories, especially meats, savories, salad dressings, as well as alcoholic and soft drinks. It is not used in perfumery work. Distribution -- native of Western Asia and the Middle East; it has a long history of cultivation all over the world, mainly for culinary use. The essential oil is produced mainly in France, Germany and Egypt from the red onion. Extraction -- essential oil by steam distillation from the bulb. Characteristics -- a pale yellow or brownish-yellow mobile liquid with strong, unpleasant, sulfur odor with a tear producing effect. Actions -- anthelmintic, anti-microbial, antirheumatic, antiseptic, antisclerotic, antispasmodic, antiviral, antibacterial, carminative, depurative, digestive, diuretic, expectorant, fungicidal, hypocholesterolemic, hypoglycemic, hypotensive, stomachic, tonic, vermifuge.
Marigolds were first discovered by the Portuguese in Central America in the 16th century. Marigolds are hardy, annual plants and are great plants for cheering up any garden. Broadly, there are two genuses which are referred to by the common name, Marigolds viz., Tagetes and Celandula. Tagetes includes African Marigolds and French Marigolds. Celandula includes Pot Marigolds. Kingdom : Plantae Division : Magnoliophyta Class : Magnoliopsida Order : Asterales Family : Asteraceae Genus : Tagetes, Calendula Marigolds come in different colors, yellow and orange being the most common. Most of the marigolds have strong, pungent odor and have has great value in cosmetic treatment. There are many varieties of Marigolds available today. Some of the major Marigold varieties are listed below: African or American Marigolds (Tagetes erecta): These marigolds are tall, erect-growing plants up to three feet in height. The flowers are globe-shaped and large. Flowers may measure up to 5 inches across. African Marigolds are very good bedding plants. These flowers are yellow to orange and do not include red colored Marigolds. The Africans take longer to reach flowering stage than the French type. French Marigolds (Tagetes patula): Marigold cultivars in this group grow 5 inches to 18 inches high. Flower colors are red, orange and yellow. Red and orange bicolor patterns are also found. Flowers are smaller, (2 inches across). French Marigolds are ideal for edging flowerbeds and in mass plantings. They also do well in containers and window boxes. Signet Marigolds (T. signata 'pumila'): The signet Marigolds produce compact plants with finely divided, lacy foliage and clusters of small, single flowers. They have yellow to orange colored, edible flowers.The flowers of signet marigolds have a spicy tarragon flavor. The foliage has a pleasant lemon fragrance. Signet Marigolds are excellent plants for edging beds and in window boxes. Mule Marigolds: These marigolds are the sterile hybrids of tall African and dwarf French marigolds, hence known as mule Marigolds. Most triploid cultivars grow from 12 to 18 inches high. Though they have the combined qualities of their parents, their rate of germination is low. Marigold (Calendula) is an extremely effective herb for the treatment of skin problems and can be used wherever there is inflammation of the skin, whether due to infection or physical damage; for example, crural ulceration, varicose veins, haemorrhoids, anal fissures, mastitis, sebaceous cysts, impetigo or other inflamed cutaneous lesions. As an ointment, Marigold (Calendula) is an excellent cosmetic remedy for repairing minor damage to the skin such as subdermal broken capillaries or sunburn. The sap from the stem is reputed to remove warts, corns and calluses.
