FROM OTHER GENERA FOR MEDICAL APPLICATIONS AND ASSOCIATES

Field of the Invention

The invention relates to cannabinoid-based compositions comprising active substances from cannabis and/or hemp in conjunction with active substances from other genera, in combination for wounds healing and thereof.

Background of the Invention

Skin wounds from injuries are uncontrollable and difficult to prevent, especially for the elderly or patients with medical condition or low immunity that small or large wounds, or scratching that cause wounds on the skin are more prone to incidence while some wounds can heal on their own. However, as some wounds may require medication and take a long time to dry and heal completely, wound dressing or wound care is of paramount importance, as can be seen in many products that help promote wound care in the form of equipment, materials, products, from devices or products for wound care and dressings, external medicine for wounds, bandages, and products to apply when the wound starts to dry so that the wound heals without scarring and it helps strengthen the skin cells in the area, as well as provide an even skin tone.

Another important aspect of wound healing is to prevent wound infection because if the wound gets infected, in addition to a longer duration of treatment, the wound may spread widely and damage the skin tissue. However, if the infection is severe or chronic, it can be widespread and difficult to heal, which may even result in the need to cut off some of the more damaged tissue. To prevent further skin damage from spreading to other areas, treatments to prevent wound infection include using herbal remedies directly and herbal medicine recipes that help in healing wounds to heal faster. According to the examination, it has been found that some pieces of work are applying for protection and are close to some composition as follows:

The Thai Petty Patent Application No. 1303000684 mentions a pharmaceutical composition for reducing the number of pathogens in infected wounds and wound healing with nutgall extract as an element by developing active substances extracted from nutgalls into a solution for use, wipe, apply or drop on wounds, especially chronic infected wounds in order to reduce or replace the use of alcohol in the treatment of chronic wound infections. The Thai Petty Patent Application No. 1603001846 refers to a cream containing herbal extracts containing false daisy extract, mangosteen peel extract, Gotu Kola extract mixed with sodium lauryl sulfate, propylene glycol, stearyl alcohol, cetyl alcohol, coconut oil, concentrated parabens, distilled water, with the following cream manufacturing processes: by extracting false daisy, mangosteen peel, and Gotu Kola and mixing the extracts at the ratio of 3:1 :1 by weight and mix with other substances, stir, and adjust the pH to be between 6.0-7.0.

The United States patent publication no. US20210236687A1 refers to a woundmanagement component containing a combination of full-spectrum cannabinoids and at least one hemostatic agent. This includes a hemostasis-level astringent, a hemostasis level, and a hemostasis mechanism level. The composition may also include at least a chemical infiltration enhancer that amplifies the absorption of cannabinoids, at least one topical drug to prolong the pharmacological activity of the cannabinoids, at least one antibacterial agent, and at least one antifungal agent, as well as means of delivery of wound management composition and kits.

The foreign patent publication no. WO2019202356A1 refers to the composition with cannabidiol supplementation and anti-inflammatory herbal extracts that inhibit COX (cyclooxygenase) and LOX (lipoxygenase), Psoralea Corylifolia or Betulin or rosemary leaf extract or licorice extract (Glycyrrhiza Glabra) with a small amount of cannabidiol of not more than 1.0% by volume. The therapeutic effect of each herbal extract contains ingredients that can be used to heal skin inflammation.

As mentioned above, it is seen that pharmaceutical composition or products containing different herbs are used to treat different wounds to meet the needs of symptoms and wounds. The inventor has invented a chemical compositions that contain active substances from cannabis or hemp for inhibiting bacteria that affects the skin in order to heal wounds, inhibit bacterial infection, help the blood to clot in order to allow the wounds to heal, and result in quick-drying and inhibiting skin irritation, particularly suitable for patients with low immunity, such as those with diabetes, shingles, and patients after surgery, etc.

Summary of the Invention

The cannabinoid-based compositions are developed to provide unique properties to help the blood clot including the inhibition of bacterial infection. The aforementioned compositions comprise active substances from cannabis or hemp together with active substances from other genera in appropriate quantities. The preparation process of the aforementioned compositions involves the extraction and purification of the compositions to be chemical compositions suitable for healing and wound healing, especially for patients with bacterial skin infection, herpesvirus, psoriasis, postoperative wounds, diabetic wounds, skin imbalances and chronic inflammation.

The purpose of this invention is to provide a cannabinoid-based composition for medical use. The unique property of such composition is function in coagulating blood together with inhibiting bacterial infection, which directly affects the healing of wounds, reducing inflammation and wound pain that may spread and damage the tissues of the wound. This makes the wound heal and the wound is covered to prevent getting pathogens faster.

Detailed Description of the Invention

The cannabinoid-based compositions for medical use contain active substances from cannabis or hemp that are effective against gram-positive, gram-negative bacteria and fungi that cause skin infections and can help reduce inflammation together with the composition of active substances of anisic acid, flavonoids, and triterpenoids that can be found from Siam weed leaves, False daisy leaves, centella asiatica, nutgall, etc., which are characterized in that they help stop bleeding, increase blood clotting to prevent and reduce blood loss from wounds, inhibit skin irritation and improve the effectiveness of wound healing, including reducing scarring.

The cannabinoid-based compositions include:

The appropriate amount of active substances from cannabis or hemp is 20-80% by weight, together with the active substances from other genera in the appropriate amount of 20-80% by weight.

The preparation process of such composition requires the extraction process with hexane, ethyl acetate or other polar solvents such as acetone, ethanol, methanol, or water or a supercritical fluid extraction method, and then, to obtain a chemical mixture, it is subjected to a purification process by precipitation.

Active substances from cannabis or hemp may be selected from any one or more of cannabinoids comprising tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), cannabigerol (CBG), cannabivarin (CBV), tetrahydrocannabivarin (THCV) and cannabi di varin (CBDV), in combination thereof. Active substances from other genera may be selected from any one or more of active substances from Siam weed leaves (Chromolaena odorata (L.) leaves), anisic acid, flavonoid, isosakuranetin, odoratin, eupatol, coumarin, false daisy leaves (Eclipta prostrata (L.) leaves, centella asiatica (Linn.), asiatic acid, asiaticosides, and madecassic acid, madecassol, nutgall extract (Quercus infectoria Olivier), tannin, gallotannin, gallic acid, ellagic acid or phenolic acid, in combination thereof.

Research results of synergistic reaction properties of cannabinoid, anisic acid, flavonoid, and triterpenoids were obtained by testing a wide range of patients, such as those with diabetes, shingles, and patients after surgery, with the cannabinoid-based composition for inhibition of skinaffecting bacteria at appropriate total concentrations. In this study, 34 patients were treated in 6 groups, 16 of which were bedridden wounds, 5 with diabetic ulcers, 9 with fresh wounds, 2 with skin and subcutaneous tendon infections, 1 with herpetic wounds, and 1 with psoriasis.

According to the research, the compositions were sent to the accredited laboratory for testing (In Vitro) to test their activity against bacteria and virus and they were found to have a beneficial effect on inhibiting gram-positive skin bacteria and herpesvirus with low concentrations for the production of the compositions for use in the treatment of patients by choosing to develop into a cream or gel form for ease of use, storage, and portability of users and with appropriate concentrations to test the side effects of skin wounds and surrounding wounds. All wounds were healed from the use of the compositions in a shorter time than patients expected compared to the length of time that patients had been treated with other medicines prior to receiving the compositions in this study, and there were no adverse effects on the wound healing and other surrounding skin as shown in the table:

In conclusion, the cannabinoid-based composition in cream or gel form can be used to treat patients with bacterial skin infection, herpesvirus, psoriasis, postoperative wounds, diabetic wounds, skin imbalances and chronic inflammation. It was observed that the rapid response phase of blood coagulation and wound healing improved within 3 to 7 days, and treatment was completed within 2-8 weeks, depending on the individual patient's condition. However, all of them recovered from the use of this composition in a shorter time than patients expected compared to the length of time patients were treated with other medicines before receiving the medicines in this study and had no side effects on the wound and other surrounding areas. As the cannabinoid-based compositions comprise active substances that provide a direct effect on healing and inhibiting pathogens, balancing the skin system, and immune system, reducing inflammation, and reducing pain, through the endocannabinoid system and a group of ion channels on the cell membrane, TRP channel cannabinoid receptors in skin sensation, homeostasis, and inflammation, the patients and their caregivers may use them to support patient care in conjunction with the current mainstream treatment. They also reduce the chance of organ loss such as in the feet and legs. In the case of patients with diabetic foot, they will recover faster and have fewer side effects from the disease. These are significant parts of gaining opportunities and holistic quality of life for patients and their caregivers. Best Mode of the Invention
