Abstract

A method of purifying herbal extract(s) from an herbaceous plant composition includes heating the herbal extracts-containing composition to volatilize at least one of herbal extract(s) into a vapor and condensing the vapor on a substrate or wet extracting the herbal extract(s) by treatment of the herbaceous plant composition or a derivative thereof with a solvent for the herbal extract(s), separating the solution of herbal extract(s), forming a concentrate and casting the concentrate on the substrate to form a coating of the herbal extract(s) on the substrate. A corresponding delivery cartridge and delivery system can include a controllable heating element and the substrate coated with at least one of herbal extract(s). These are configured to allow passage of air over the substrate to volatilize or entrain the herbal extract(s) as a vapor, gas or aerosol for administration to a user.

Claims

1. An herbal extract delivery product comprising:

a substrate coated with one or more layers of one or more herbal extracts of one or more herbaceous plants.

2. An herbal extract delivery product of claim 1 further comprising:

a coated substrate with one or more coating layers, the one or more coating layers including one or more herbal extracts; and

a heating element for heating the coated substrate to a temperature to volatize or entrain the one or more herbal extracts on the one or more coating layers into one or more vapors or aerosols inhalable by a user.

3. An herbal extract delivery product of claim 2 further comprising multiple coating layers, each layer being a different herbal extract.

4. An herbal extract delivery product of claim 2 further comprising segregated layers of herbal extracts having a coterminous arrangement such that the layers are free from overlap.

5. An herbal extract delivery product of claim 2 further comprising a control element for the heating element that controls the time and temperature of heating.

6. An herbal extract delivery product of claim 5, further comprising:

A cylindrical structure extending in a longitudinal direction and formed from a substrate of an electrically conductive material, the cylindrical structure comprising;

At least a first set of electrodes extending longitudinally and laterally on the substrate, the at least first set of electrodes having an electrical resistance sufficient to conduct current laterally along the substrate;

An at least first substrate portion coterminous with the at least first set of electrodes, the first substrate portion having an electrical resistance high enough to conduct current from the first set of electrodes and resistively heat the first substrate portion in response to the current conducted there through; and

At least a first dose of an herbal extract disposed on the first substrate portion and configured to volatilize or entrain into a gas or aerosol in response to the resistive heating of the first substrate portion.

7. An herbal extract delivery product of claim 1 further comprising herbal extracts of herbaceous plants selected from the group consisting of damiana, blue lotus, mullein, lobelia, peppermint, spearmint, catnip, thyme, sage, wild dagga, lavender, rosemary, salvia divinorum, basil, lemon balm, hops, yerba mate, calea zacatechichi, chamomile, ashwagandha eucalyptus, passion flower, St John'"'"'s wart, valerian, astragalus, avena sativa, kinnikinnick, cacao, chago, cinnamon, nutmeg, mace, cordyceps, Don Quai, Gotu Kola, ginger root, ginseng, green tea, kava, maca, moringa leaf, mullein, sacred pink lotus, red raspberry, rhodiola, rooibos, tong kat ali, vanilla, yohimbine, garlic, turmeric, nutmeg, capsaicin, rosemary, cannabis, coniferous trees, yew bush, willow tree, aspen tree, blood root, opium poppy, atropa belladonna, strychnine, vinca rosea, coffee plant, cacao tree and beans (chocolate), coca plant (cocaine), nicotinaa tabacum, camelia sinensis, monkshood, castor oil, henbane, calabar bean, digitalis sp, autumn crocus, peyote, amanita, orange, lemon, and any other known herbaceous plants which produce known agents having useful medicinal, pharmacological, physiological, beneficial, sensory or other perceived measurable effects on humans.

8. A method of making an herbal extract delivery product, the method comprising:

Heating an appropriate herbaceous plant part to a temperature to volatize an herbal extract into a vapor;

9. A method for producing a substrate coated with one or more herbal extracts, comprising

a. Comminuting herbaceous plant material to produce particulate material

b. Extracting the particulate plant material with a solvent in which the herbal extract is soluble to produce a solution;

c. Concentrating the solution to produce a concentrate;

d. Depositing the concentrate on the substrate; and

,

e. Evaporating the solvent from the concentrate to produce a coating of the herbal extract on the substrate;

f. Optionally repeating steps a-e to produce multiple layers of herbal extracts on the substrate.

11. A method of claim 9 further comprising herbal extracts of herbaceous plants selected from the group consisting of damiana, blue lotus, mullein, lobelia, peppermint, spearmint, catnip, thyme, sage, wild dagga, lavender, rosemary, salvia divinorum, basil, lemon balm, hops, yerba mate, calea zacatechichi, chamomile, ashwagandha eucalyptus, passion flower, St John'"'"'s wart, valerian, astragalus, avena sativa, kinnikinnick, cacao, chago, cinnamon, nutmeg, mace, cordyceps, Don Quai, Gotu Kola, ginger root, ginseng, green tea, kava, maca, moringa leaf, mullein, sacred pink lotus, red raspberry, rhodiola, rooibos, tong kat ali, vanilla, yohimbine, garlic, turmeric, nutmeg, capsaicin, rosemary, cannabis, coniferous trees, yew bush, willow tree, aspen tree, blood root, opium poppy, atropa belladonna, strychnine, vinca rosea, coffee plant, cacao tree and beans (chocolate), coca plant (cocaine), nicotinaa tabacum, camelia sinensis, monkshood, castor oil, henbane, calabar bean, digitalis sp, autumn crocus, peyote, amanita, orange, lemon, and any other known herbaceous plants which produce known agents having useful medicinal, pharmacological, physiological, beneficial, sensory or other perceived measurable effects on humans.
