FIG. 2 is a side perspective or elevation view of the vessel of FIG. 1 in use according to the invention.[0018]

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

Preferred aqueous solutions according to the invention are disclosed. The solutions can be packaged in any size according to desire. However, according to the methods of the invention concentrated solutions are preferred. In the preferred example herein a two-ounce bottle is selected for distribution to consumers. The bottle contains 59 milliliters (ml) of solution. The concentrations for the preferred constituents will be given for the concentrated 59 ml solution. These concentrations will of course be different when and if a consumer dilutes the original solution according to preferred methods of use. [0019]
An exemplary solution contains 465 milligrams of Zinc Acetate U.S.P. or about 7.88 mg/ml of aqueous solution. The aqueous solution also contains: about 0.115 ml. of phellodendron bark (phellodendron amurense) extract which is about 2:1 weight to volume or 0.001955 ml/ml of solution; about 0.0385 ml of cultivated goldenseal root ([0020] hydrastis canadensis) extract (about 2:1 weight/volume) or 0.00065 ml/ml of solution; 0.0385 ml of barberry root bark (berberis vulgaris) extract (about 2:1 weight/volume) or about 0.00065 ml./ml.; about 0.0385 ml of coptis root (coptis chinensis) extract (2:1 weight/volume) or about 0.00065 ml/ml of solution; 0.05369 ml of grapefruit seed extract or about 0.00130 ml/ml of solution; about 0.02301 ml of glycerol (from vegetables); and, about 0.00039 ml/ml of solution.
The herbs or plants listed above are preferably, initially extracted with a hydro-alcoholic base (purified water and U.S.P. grade ethyl alcohol from corn) at a weight/volume ratio of about 1:4. The weight/volume ratio determines the strength of the herbal extract. A ratio of 1:4 is classified as a tincture. The tincture is then filtered and concentrated using a low-heat static process which removes all of the alcohol to a weight/volume ratio of 2:1. Then these extracts are blended (optionally with the other ingredients, such as zinc acetate dihydrate) very thoroughly in the base carrier ingredient which is preferably distilled, micro-filtered, ozonated water. [0021]
It will be understood by those of ordinary skill in the art that, the weight to volume ratio is a standard scale used to indicate the strength of a tincture or extract. Technically an extract is stronger than a tincture. The standard is represented by weight, which indicates the amount of herb material used to volume, which indicates the amount of menstrum or solvent (usually a mixture of water and grain alcohol of which the proportions are determined the sought after plant constituents). For example, a 1:1 weight to volume ratio indicates that 8.33 pounds of herb or botanical material is used per gallon of solvent, while a 2:1 weight to volume ratio indicates 16.33 pounds of herb is used per gallon of solvent. A 1:4 weight to volume ratio indicates that 8.33 pounds of herb is used per 4 gallons of solvent and so on. [0022]
Families of beneficial alkaloids for the solution may be derived (such as extracted by the above or other known means) according to the following naturally occurring families per plant, or combinations of alkaloids between plants (that is, their combination between alkaloids of different plants or “herbs”). For example, a naturally occurring family of alkaloids exist in each of the following plants (or herbs): Oregon grape root contains berberine, oxyberberine, and berbamine; yellow root contains berberine; phellodendron bark contains berberine, palmatine, magnoflorine, phellodendrine, jateorrhizine, candicine, and menisperine; coptis rhizome contains berberine, coptisine, palmatine, jateorrhizine, worenine, magnoflorine, columbamine, and epiberberine alkaloids; goldenseal root contains hydrastine, berberine, canadine, canadaline, and hydrastidine; barberry root contains berberine, oxycyanthine, berbamine, berberrubine, palmatine, isotetrandine, jateorrhizine, and columbamine; and, Indian barberry root bark contains berberine alkaloid. [0023]
Each of these plants contains its own family of alkaloids, and therefore according to the invention can provide a beneficial family on its own. Also, according to the invention, a mixture or family of alkaloids comprised of the alkaloids from differing plants can provide beneficial solutions. [0024]
It is also contemplated that the following constituents in various combinations with those claimed and disclosed herein would provide further advantages according to the invention for nasal treatment and solutions therefore: colloidal silver (at least 30-100 parts per million with a micron size of 0.001), pure sodium chloride (99.99% pure); and, essential oils of peppermint, eucalyptus, oregano, thyme, lemon, lime, orange, grapefruit, lemon grass, geranium, palma rosa, lavender, bergamot, pine, tea tree, sandalwood, and rosemary. Other herbs or their extracts such as [0025] echinacea angustifolia, echinacea purpurea, and echinacea pallida are also contemplated.
Numerous reports and studies show support for the antimicrobial activity of the major berberine containing plants. The berberine alkaloid has been shown to be active in vitro against the growth of organisms like streptococci, staphylococci, and pneumococci. Ethanol extracts of berberine containing plants have shown strong anti-inflammatory properties in many clinical investigations. Results from various clinical investigations into the major isolated alkaloids of Goldenseal root have provided a rational basis for the traditional antibacterial uses of this root. [0026]
While berberine and hydrastine, provide benefits according to the invention, it was discovered that the constituents disclosed herein provide synergistic compositions in which all of the ingredients compliment each other and work more effectively together than alone by themselves. For example, in the formulation and development of solutions according to the invention, it was also noted that with the addition of the Berberine containing herbs, the astringent qualities of the solutions increased. Subsequent inclusion of grapefruit seed extract in compositions incrementally increased the astringency level of the previous formula. In fact, each of the individual ingredients were used at one point individually during the earlier research stages and were empirically found to be less effective when used alone as opposed to a composition of two or more of the ingredients. [0027]
Various forms of Zinc were investigated in order to best scrutinize this element against human health ailments as well as effectiveness and stability in solutions according to the invention. [0028]
In certain preferred solutions according to the invention, Zinc plays several major roles functionally in the composition. Studies have shown that various types of Zinc help the body and immune system shorten the duration of common colds and reduce common cold symptoms while aiding in overall immune function. Zinc also assists and enhances the bodies' ability to heal wounds and maintain overall health and well being. [0029]
Much research has been done on zinc in variously administered forms and has demonstrated that zinc can cut the duration of common cold symptoms by half in many cases. This body of research on zinc has shown to speed the recovery of the physiology when invaded by a cold or flu. In-vitro laboratory studies have shown that zinc may interfere with the reproductive process of various viruses known to cause colds (i.e. rhinoviruses). Similar in-vitro inspections with zinc have shown that it may interfere with the ability of certain viruses to enter the cells of the body. [0030]
In use with the present invention, it was shown that zinc acetate in combination with the other constituents is more effective than other means of administration due to the direct topical application and saturation of portions of sinus physiology, which is achieved for at least 30 seconds when applied according to the methods of this invention. This direct saturation leads to greater astringency and mucosal absorption of zinc and the other components in the solution. [0031]
It was also discovered during the development of solution compositions according to the invention that having zinc in the solution and particularly zinc acetate, showed (through organolapetic means, primarily taste), that the solution was exceptionally astringent and drying. [0032]
Others have provided means for delivering various beneficial components to the nasal passages via sprays, inhalants, and the like. These methods are deficient at reaching many portions of the sinus and do not provide optimal exposure of the active ingredients to nasal tissue. Accordingly it was proposed to provide solutions according to the invention to the nasal passages by streaming the solutions into an out of the passages. It is proposed that, for a given total amount of active ingredient to be dosed to a nasal passage, exposure to the tissue is increased by diluting the amount in a solvent but then streaming the entire amount (as the dilute solution) over the desired nasal tissue. [0033]
FIG. 1 discloses a [0034] vessel 10 for practicing methods according to the invention. According to a preferred method of the invention, vessel 10 is filled with a diluent or carrier such as water or saline solution, and a desired amount of a solutions according to the invention is added. The resulting dilute solution is then flowed through at least a desired portion the nasal cavities.
As disclosed in FIG. 2, a preferred method of irrigation includes flowing the solution into a first nostril while discharging the solution through a second nostril. The [0035] vessel 10 has a port or spout 12 which cooperates with a nostril to provide an acceptable degree of sealing between the vessel and the first nostril. The method includes positioning the nostril and the vessel 10, with respect to each other such that either gravity or ambient air pressure will flow the solution from the vessel 10 into the first nostril and out of the second nostril. The vessel 10 preferably hold about 8 oz of dilute solution, all of which is flowed through the nasal cavities. Using solutions of the concentrations disclosed herein, it is preferable to add between 1-10 ml, and more preferably about 3-5 ml, per 8 oz of diluent, such as for vessel 10.
Either larger vessels or repeated applications may be desired for additional irrigation. [0036]
