Botanical Name:  Norwegian Kelp.

Domain: Eukaryota

Kingdom: Protista

(unranked): Chromista

Phylum: Heterokontophyta

Class: Phaeophyceae

Order: Fucales

Family: Fucaceae

Genus: Ascophyllum

Species:
A. nodosum

Norwegian Kelp is a large, common, brown alga, in the Class Phaeophyceae. It is seaweed of the northern Atlantic Ocean, also known as Ascophyllum nodosum, Knotted Kelp, knotted wrack or egg wrack. It is common on the north-western coast of Europe (from Svalbard to Portugal) including east Greenland and the north-eastern coast of North America.

It is is very popular amongst the science community and has been claimed to be both the best known seaweed on the planet as well as the most researched by the academic community

Kelp (acophyllum nodosum) is a seaweed with a long history of use as a food and as a source of assimilable iodine. Ascophyllum nodosum is a species of kelp that only grows deep in ocean waters. Other off shore kelps may absorb heavy metals and toxins. That is why Now Foods kelp is wild grown Norwegian Kelp, and is comprised only of valuable nutrients from ocean floors. We use the whole dried kelp plant.

Kelp is a large, leafy brown algae that belongs to the seaweed family and grows in the colder waters of the world’s oceans. It is a good source of marine minerals, including potassium, magnesium, calcium and iron. It is also an excellent source of iodine, which has been shown to support healthy thyroid function. Your thyroid gland is responsible for producing the hormones that support normal cellular metabolism. As with most green foods, kelp also contains vitamins and cell salts essential for good nutrition.*

Description and ecology:
Ascophyllum nodosum has long fronds with large egg-shaped air-bladders set in series at regular intervals in the fronds and not stalked. The fronds can reach 2 m in length and are attached by a holdfast to rocks and boulders. The fronds are olive-brown in color and somewhat compressed but without a mid-rib.

This seaweed grows quite slowly and can live for several decades; it may take approximately five years before becoming fertile.

Life history is of one diploid plant and gametes. The gametes are produced in conceptacles embedded in yellowish receptacles on short branches.

Ascophyllum nodosum is found mostly on sheltered sites on shores in the mid-littoral where it can become the dominant species in the littoral zone.

Polysiphonia lanosa (L.) Tandy is a small red alga, commonly found growing in dense tufts on Ascophyllum whose rhizoids penetrate the host. It is considered by some as parasitic.

Varieties and forms:
Several different varieties and forms of this species have been described.

Ascophyllum nodosum var. minor has been described from Larne Lough in Northern Ireland.
There are free floating ecads of this species such as Ascophyllum nodosum mackaii Cotton, which is found at very sheltered locations, such as at the heads of sea lochs in Scotland and Ireland.

The species is found in a range of coastal habitats from sheltered estuaries to moderately exposed coasts, often it dominates the inter-tidal zone (although sub-tidal populations are known to exist in very clear waters). However it is rarely found on exposed shores, and if it is found the fronds are usually small and badly scratched.

It has been recorded as an accidental introduction to San Francisco, California, and eradicated as a potential invasive species there.

Distribution
Recorded in Europe from: Faroe Islands, Norway, Ireland, Britain and Isle of Man Netherlands North America: Bay of Fundy, Nova Scotia, Baffin Island, Hudson Strait, Labrador and Newfoundland.

Uses:
Ascophyllum nodosum is harvested for use in alginates, fertilisers and for the manufacture of seaweed meal for animal and human consumption. It has long been used as an organic and mainstream fertilizer for many varieties of crops due to its combination of both macronutrient, (eg. N, P, K, Ca, Mg, S) and micronutrients (eg. Mn, Cu, Fe, Zn, etc.) It also host to cytokinins, auxin-like, gibberellins, betaines, mannitol, organic acids, polysaccharides, amino acids, and proteins which are all very beneficial and widely used in agriculture.

Ascophyllum nodosum along with Macrocystis pyferais harvested in Ireland, Scotland and Norway from which alginates are extracted it is one of the world’s principal alginate supply.

Medical Uses:
A long history of use as a source of assimilable iodine. Some benefits include:
– Contains many nutrients absorbed from the sea.*
– Naturally Pure Wild Grown Norwegian Kelp
– Natural Potency of Iodine.

Norwegian Kelp may reduce, or even eliminate, not only bacterial plaque and dental caries but also arteriosclerotic plaque, atherosclerotic plaque, pleural plaque, renal calculus, biliary calculus, and prostatic calculus.

Furthermore, the medicinal and dental uses have been recognized for well over a century.

Seawater Spray Cures Kids’ Colds

[amazon_link asins=’B0078ITD14,B01DVO77BG,B0078IT4SQ,B00E67ARCO,B0052ECL2O,B0083PZZBI,B00DX5MINQ,B00FP31IW6,B01KYQ3OCK’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’fc0fa1fe-13a3-11e8-a2a5-893c904582fb’]

For parents worried about how to treat children’s colds now that some medicines have been called into question, the answer may be a dose of salt water..CLICK & SEE

A nasal spray made from Atlantic Ocean seawater eased wintertime cold symptoms faster and slowed cough and cold symptoms from returning among children ages 6 to 10, researchers in Europe reported on Monday.

It may be that the salt water has a simple mechanical effect of clearing mucus, or it could be that trace elements in the water play some more significant role, though the exact reason why such a solution works is not known, said Dr Ivo Slapak and colleagues at the Teaching Hospital of Brno in the Czech Republic.

The study, published in the January issue of the Archives of Otolaryngology, was paid for by Goemar Laboratoires La Madeleine, Saint-Malo, France, which makes Physiomer, the seawater nasal spray used in the investigation.

The authors said that while saline washes have long been mentioned as a treatment for colds, scientific evidence about whether they work is poor.

The report was published days after the US Food and Drug Administration said children under two should not be given nonprescription cough and cold medicines because they are too dangerous for that age group, with deaths, convulsions and rapid heart rates reported in rare cases.

US health officials have not yet decided if the widely sold medicines made by companies such as Wyeth and Johnson & Johnson are appropriate for older children, and have said they hope to have a ruling covering appropriate use for children 2 to 11 later this year.

The American Academy of Pediatrics has said cough and cold products are ineffective for children under age six, and may also be risky. The Czech study involved 390 children with uncomplicated cold or flu symptoms.

‘Smokable’pain drug for faster relief

[amazon_link asins=’B01LTI0Z7O,B004Z9DE50,B0716XFJJB,B01N2UUHBO,B01MXDNG39,B01H4XMDPA,B00JLJ2WDY,B00DNMZH4G’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ff0e6848-606f-11e7-9e41-27e6d86695f2′]

All self-respecting painkillers these days offer “fast-acting relief,” a promise we accept to mean anywhere from 15 minutes to more than an hour.

For Alexza Pharmaceuticals Inc, which is developing drugs for migraine, pain, panic and agitation, ‘fast’ has to mean ‘within seconds.’

The Palo Alto, California-based company is developing drugs that can be “smoked,” and, like nicotine in cigarettes, pass through the lungs and into the bloodstream almost instantly. Investors like the idea.

Alexza’s shares have risen nearly 60% over the past five months, dramatically outperforming the Nasdaq Biotechnology Index, which rose 15% over the same period.

“What makes this an exciting story is how broadly applicable the technology could prove to be,” said Charles Duncan, an analyst at JMP Securities, which helped take the company public for $8 a share a year ago.

Alexza was formed by biotechnology entrepreneur Alejandro Zaffaroni, who also founded nicotine-patch developer Alza. His latest venture is not the only company that is developing inhaled therapies: Nektar Therapeutics and Alkermes Inc develop powdered insulin.

But Alexza’s idea of heating up a drug to create a vapour, or smoke, is unique.The company’s lead product is a vaporised version of an old drug called prochlorperazine, which Alexza is developing for migraine headaches but is currently used in liquid, oral or suppository form to treat severe nausea.

While it is sometimes given intravenously in hospitals to treat patients with acute migraines, the drug is inconvenient to deliver.

Alexza is hoping to provide similar results but in such a way that patients can carry the delivery device — an inhaler that looks like a miniature hip flask — in a pocketbook or the glove compartment of a car.

The device contains a battery-powered package that heats a thin coating of drug to create a vapour that can be sucked into the lungs.

“It’s a useful mode of delivery, though its desirability and frequency of prescription will depend on the disorder,” said Jeffrey Lieberman, chairman of psychiatry at Columbia University.

The company plans to release initial results of a mid-stage clinical trial of its migraine drug by the end of March. If all goes according to plan, Alexza could file a marketing application with US regulators in 2010.

The company is also testing inhalable drugs for pain and anxiety, and for agitation in schizophrenia patients.

While Lieberman doubts there would be much demand for an inhaled product for agitated schizophrenia patients, who would be unlikely to cooperate in taking it, he said there could be benefit for patients with migraine, panic and pain.

“People with panic disorder want immediate relief and would be very cooperative,” Lieberman said. “They know that if they take a pill it can take up to an hour to work. This would be a non-stigmatising way to deal with the situation.”

Thomas King, Alexza’s chief executive, said the company expects to announce a partnership with either a major drugmaker or specialty pharmaceuticals or device company to help develop at least one drug during the second half of this year.

“The key is to find partners with the same passion for the technology and what it conveys as we do,” he saiD.
