Disclosed herein are embodiments of cannabis extraction methods, apparatuses for extracting cannabis, and methods of using cannabis extracts.

The present invention provides a composition for preventing, improving or treating periodontal diseases comprising extract of mangosteen.

The composition of the present invention has excellent anti-bacterial and anti-inflammatory effects against bacteria inducing periodontal diseases as comprising extract of mangosteen, or alpha-mangosteen or gamma-mangosteen derived from thereof, and thereby it can be widely used for medicines and foods for preventing, improving or treating periodontal diseases.

The present invention provides a pharmaceutical composition for adjunctively treating cancer. Differing from conventional therapies commonly using anti-cancer drugs and/or radiation substances to cause the apoptosis of cancer cells, the present invention particularly adopts an ethanol extract of Taiwanofungus camphorata (TCEE), an ethanol extract of Ganoderma lucidum (GLEE) or a combination of the TCEE and the GLEE as the a novel pharmaceutical composition for causing the apoptosis of lung cancer cells A594, hepatoma cells Huh 7, breast cancer cells MDA-MB 231, and colorectal cancer cells HT 29. Moreover, differing from conventionally-used anti-cancer drugs and radiation substances always causing some side-effects such as nausea, vomit, and poor appetite, this novel pharmaceutical composition can not only be used for adjunctively treating cancer, but also possesses many healthy effects, including: detoxification, enhancing immunity, and increasing appetite.

A method for preventing or treating at least one of depression and anxiety disorder according to an embodiment of the present invention includes administering to a subject in need thereof a composition having an extract of Fraxinus rhynchophylla as an effective ingredient. By having an effect of improving depressive behavior and low physical activity shown in an animal model with induced anxiety and depression, reducing the level of cortisol, increasing the level of serotonin, and also increasing the expression amount of pCERB, BDNF, and mBDNF proteins in hippocampal tissues, the compositions can be advantageously used for developing a functional health food product or a pharmaceutical product for ameliorating or treating the depression and anxiety disorder.

A pharmaceutical or cosmetic composition comprising an Indigo Naturalis or Indigo-producing plant extract for treating atopic dermatitis and any form of eczema, and a method of treating atopic dermatitis comprising administering a therapeutically effective amount of an Indigo Naturalis or Indigo-producing plant extract to a subject in need thereof are described.

The present invention relates to synergistic compositions for the treatment of one or more associated conditions of arthritis or rheumatoid arthritis osteoarthritis. More particularly, novel synergistic compositions which comprises a combination of therapeutically effective amounts of: a) an alcoholic/hydroalcoholic extract of Tamarindus indica seed comprising proanthocyanidins either alone or in combination with water extract of Tamarindus indica seed comprising polysaccharides, b) a Curcuma longa rhizome extract comprising curcuminoids, c) optionally containing pharmaceutically or nutraceutically or dietetically acceptable carriers/excipients. The invention also relates to a method of treating one or more associated conditions of arthritis or rheumatoid arthritis or osteoarthritis using synergistic composition.

An oral spray formulation using an Ixeris dentata Nakai extract as an active ingredient of a composition for preventing and treating xerostomia occurring as a diabetic complication, particularly an oral spray formulation capable of administering a drug through a simple and rapidly absorbable route is provided. The secretion of saliva is reduced as cells from a submandibular gland tissue of a diabetes model animal are destroyed. However, when the Ixeris dentata Nakai extract of the present invention is sublingually sprayed into a sublingual region of the diabetes model animal, expression levels of α-amylase, AQP5 and NHE1 can significantly increase, resulting in an increased secretion quantity and rate of saliva.

When the Ixeris dentata Nakai extract is administered using the formulation of the present invention, the Ixeris dentata Nakai extract is sublingually sprayed through the spray formulation, and thus can be directly locally administered to a salivary gland tissue having an activity to induce secretion of saliva. Therefore, saliva secretion can be induced by rapid absorption of the active ingredient of the Ixeris dentata Nakai extract in the salivary gland tissue without any absorption process through the digestive system, resulting in minimized side effects.

A method of treating hypertension can include administering to a patient in need thereof a therapeutically effective amount of an extract of Matricaria chamomilla L. The extract can be administered orally to the patient in an amount of about 100 mg/kg to about 200 mg/kg.

The invention discloses a method for extracting high-purity asarinin and use thereof. The method comprises: putting crude asarum powder in an SFE-CO.sub.2 device; under the conditions that an extraction kettle has a pressure of 30-40 Mpa and a temperature of 45-70° C., separating kettles I and II have a pressure of 5-10 Mpa, a temperature of 30-50° C. and the flow rate of CO.sub.2 is 35-60 L/h, extracting for 60-240 min to obtain total volatile oil of asarum; standing the total volatile oil of asarum for 24-72 h at a low temperature, and carrying out suction filtration under reduced pressure to obtain crude asarinin; and re-crystallizing the crude asarinin in absolute ethanol twice to obtain pure asarinin. It is found for the first time that asarinin has a good cough-relieving activity and thus can be used in preparing medicines for treating various types of coughs.

The present invention provides a method of isolating at least one ingredient with anti-viral efficacy from Baphicacanthus cusia. The ingredient can be an alkaloid, a triterpenoid, a lignan, a phenylethanoid, a sesquiterpene lactone, or a flavonoid. Two new alkaloids are produced, which have not been previously reported. Moreover, the method isolates 12 compounds which could not or have not been previously isolated. A pharmaceutical composition includes the at least one ingredient and at least one pharmaceutical tolerable excipient. A method of treating a subject suffering from a viral disease includes administering at least one ingredient isolated from Baphicacanthus cusia.
