Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a flowchart illustrating steps that may be followed, in accordance with one embodiment of a method or process of manufacture of an herbal combination composition.

DETAILED DESCRIPTION

(2) Before describing the invention in detail, it should be observed that the present invention resides primarily in a novel and non-obvious combination of elements and process steps. So as not to obscure the disclosure with details that will readily be apparent to those skilled in the art, certain conventional elements and steps have been presented with lesser detail, while the drawings and specification describe in greater detail other elements and steps pertinent to understanding the invention.

(3) The following embodiments are not intended to define limits as to the structure or method of the invention, but only to provide exemplary constructions. The embodiments are permissive rather than mandatory and illustrative rather than exhaustive.

(4) In the following, we describe the structure of various embodiments of an herbal combination composition and methods for its manufacture.

(5) In various embodiments, the herbal combination composition can be a mixture, including a powder, which can be a granule powder; a syrup, emulsion, or suspension with an established viscosity, color, pH and flavors. Oily parts must be dispersed into fine globules within syrup with the help of an emulsifying agent. Therefore, an acceptable formulation cannot be achieved simply by a juice mixer technique. It needs step wise control and testing during manufacturing till a stable formulation is achieved for a shelf life stability testing at various temperatures and relative humidity to mimic shelf life conditions of different countries. Higher temperature and relative humidity study is an alternative to have an accelerated study for a short period of time to apply a linear regression for the extrapolated time period. Once studies are successfully completed, then the data is considered as the new knowledge to satisfy the claim labels of the active pharmaceuticals in the mixed formulation.

(6) In related embodiments, microbial and fungal contamination control of the herbs are other major challenges as the source of the herbs are natural agricultural fields rather than a controlled manufacturing of a chemical plant. A specific preservative or a combination of preservatives in the correct quantities needs to be selected and employed based on the incoming quality of raw herbal extracts from the extract manufacturers; to avoid any fungal or microbial growth in the combined formulation.

(7) In further related embodiments, in order to make stable formulations the particulate size of the herb extracts needs to be maintained and particles larger than 0.5 micron needs to be eliminated by filtration to avoid suspension, and segregation.

(8) In other further related embodiments, solubilizing different moieties of the extracts is not as simple as one or few molecules of the active pharmaceuticals. It needs the use of co-solvents, solubilizes, chelating agents, emulsifying agents and experimenting those until an optimized combination is satisfied. A new knowledge establishes here as the part of the invention.

(9) In further related embodiments, an herbal combination composition can include chelating agents, co-solvents, preservatives, solubilizes, and other excipients. Polyethylene glycol 1000, or PEG 600-1000, can be included to thicken a syrup with Xanthan gum to establish a target viscosity of the syrup.

(10) In a further related embodiment, an acetate buffer and/or citric acid can be used to maintain pH of the herbal combination composition around 5.0.

(11) In further related embodiments, a high shear mixing technique can be used to produce a homogenized solution, such as shown in the process flow diagram depicted in FIG. 1. Heating/Cooling and RPM of the agitators can be varied to adjust the process and hot water jacketed heating and cooling can be configured at different levels of the manufacturing as defined in the process flow diagram shown in FIG. 1.

(12) In a related embodiment, the herbal combination composition can be formulated for diabetic patients, such that the herbal combination composition includes artificial non sugar based sweetener, such as saccharine sodium, sucralose, etc.

(13) In various embodiments, the herbal combination composition can include Hyssop, Ginger, Viola Odorta, jujube, chamomile, Holy Basil (Ocimum tenuiflorum), having the following characteristics: a) Hyssopus officinalis (Hyssop) has been indicated in the Natural Medicines for cough, common cold, respiratory infections, and sore throat. It is considered GRAS (generally recognized as safe) by the US Food and Drug Administration; b) Zingiber officinale (Ginger) is reported as GRAS by the FDA. It has been indicated in the natural medicines for upper respiratory tract infections, cough, bronchitis, nausea, and headache. The active part of ginger is ginger root. It includes gingerol, gingerdione, shogaol, sesquiterpine, and monoterpene volatile oils. c) Viola odorata (Sweet violet) is indicated in the natural medicines for chronic and acute bronchitis, bronchial asthma, acute and chronic mucous inflammation, cold symptom hoarseness, chest spastic and whooping cough; d) Ziziphus jujuba (Jujube or red date) is indicated for cold and cough; especially the calming nature has reported providing stress relief, and promoting sleep; e) Chamomile, which can include extracts of various species of Asteraceae, is reported as GRAS by the FDA. Chamomile extract has been indicated for respiratory tract irritation, allergic rhinitis, and nasal membrane inflammation; f) Holy Basil (Ocimum tenuiflorum) has been indicated for its short term (4 to 6 weeks) use as a safe remedy for common cold, influenza, swine flu, asthma, bronchitis, and fever because of its anti-infective properties.

(14) In related embodiments, a detailed scientific review of the herbal constituents has provided support for selecting and optimize these herbs in the range of 1-2% individually of the clinical dose, not exceeding more than 7% of the total herbal content. Formulation was put on a long term stability study at 25±2 degree Celsius and relative humidity of 60±5% as required by United States Pharmacopeia. The label claimed potency was found within 110% and 90% of the label claim at 21 months long term samples.

(15) Development and research of related embodiments, led to development of a robust analytical spectroscopic High Pressure Liquid Chromatography method to test each sample for all active pharmaceuticals in the presence of all herbal constituents and excipients with highest clear resolution of each individual active ingredient.
