     Description of the Related Art 
     The smoking of various herbs can provide physiological and/or psychological effects, some of which can provide therapeutic benefits. For example,  cannabis , also known as marijuana, is an herb that can be smoked for recreational purposes or therapeutic purposes, such as to treat nausea, pain, muscle spasticity, and loss of appetite, among other conditions. It has been observed that different herbs, including different species, different strains, or different varieties of an herb can have different therapeutic effects. Consequently, different species, strains, or varieties of herbs have been cultivated to achieve desired effects. Such cultivation, however, can be time-consuming, can limit the availability herbs with a desired effect, and may be cost-prohibitive for rare or difficult to cultivate plants. 
     Accordingly, there is a continuing need for methods of providing smoking herbs with desired effects. 
     SUMMARY

     DETAILED DESCRIPTION 
     Since the discovery of therapeutic effects of inhaled smoke of  cannabis , the chemical origins of the therapeutic effects have been an intense area of research. The primary focus of the research into the chemical origins of the therapeutic effects of  cannabis  has been centered around a class of active compounds called  cannabis  phytocannabinoids. Phytocannabinoids, also referred to as cannabinoids, refer to a group of C 21  terpenophenolic compounds that are uniquely produced in  cannabis . The most widely known phytocannabinoid is tetrahydrocannabidol (THC), which is known to be responsible for producing psychoactivity commonly associated with  cannabis . Since the isolation of THC, other phytocannabinoids have been isolated and some have been associated with therapeutic effects. While over 100 phytocannabinoids are known to exist, a group of well-documented phytocannabinoids include tetrahydrocannabidol (THC), cannabidiol (CBD), cannabichromene (CBC), cannabigerol (CBG), tetrandrocannabivarin (THCV), cannabidivarin (CBDV) and cannabinol (CBN). Some of the therapeutic effects of phytocannabinoids include, without being bound to any theory, euphoric effects (associated, for example, with THC and THCV), analgesic effects (associated, for example, with THC, CBD and THCV), sedative effects (associated, for example, with CBD), antipsychotic effects (associated, for example, with CBD), anti-inflammatory effects (associated, for example, with THC, CBD, CBC, CBG and CBN), anti-convulsant effects (associated, for example, with CBD and CBN), anti-biotic effects (associated, for example, with CBC, CBN and CBG), and anti-fungal effects (associated, for example, with CBC and CBG), to name a few. Under certain circumstances, there may be synergistic enhancement of certain therapeutic effects in naturally occurring  cannabis  when certain amounts and/or ratios of phytocannabinoids are present in combination. For example, an overall enhancement in therapeutic effects of  cannabis  may be achieved when a certain balance is struck between THC and CBD. For example, sedative effects of CBD may serve to oppose certain undesirable effects of THC, such as anxiety, thereby enhancing the overall therapeutic effects. 
     Other isolated compounds of  cannabis  may have certain therapeutic effects when inhaled as part of  cannabis  smoke, including terpenoids, flavonoids, and phytosterol. Terpenoids are derived from repeating units of isoprene (C 5 H 8 ), such as monoterpenoids (with C 10  skeletons), sesquiterpenoids (C 15 ), diterpenoids (C 20 ), and triterpenoids (C 30 ). The final structure of terpenoids can range from simple linear chains to complex molecules and may simply be a hydrocarbon, or may include alcohol, ether, aldehyde, ketone, or ester functional groups attached to a carbon skeleton. As used herein, the term terpenoids include terpenes. Over 200 naturally occurring terpenoids have been identified and isolated from  cannabis . Such terpenoids include d-limonene, α-pinene, β-myrcene, linalool, pulegone, 1,8-cineole (eucalyptol), α-terpineol, terpineol-4-ol, p-cymene, borneol, Δ-3-carene, β-caryophyllene, caryophyllene oxide, nerolidol, and phytol. Some of the therapeutic effects of terpenoids include, without being bound to any theory, analgesic effects (associated, for example, with β-myrcene), sedative effects (associated, for example, with linalool, pulegone and α-terpineol), antidepressant effects (associated, for example, with linalool and d-limonene), anti-inflammatory effects (associated, for example, with β-myrcene, β-caryophyllene, 1,8-cineole, α-pinene and Δ-3-carene), anti-mutagenic effects (associated, for example, with β-myrcene and d-limonene), anti-biotic effects (associated, for example, with β-myrcene, 1,8-cineole, p-cymene, terpineol-4-ol, borneol and α-pinene), and Acetylcholinesterase (AChE) inhibitor effects (associated, for example, with pulegone, p-cymene, terpineol-4-ol and α-terpineol), to name a few. It will be appreciated that, under certain circumstances, there may be synergistic enhancement of certain therapeutic effects in naturally occurring  cannabis  when certain amounts and/or ratios of terpenoids are present in combination. 
     In addition, under certain circumstances, when phytocannabinoids and terpenoids are simultaneously present in  cannabis , there may also be cross-compound synergistic effects. That is, the therapeutic effects obtained from  cannabis  having certain combinations of some phytocannabinoids and some terpenoids is greater than the sum of therapeutic effects obtained from the phytocannabinoids or the terpenoids taken alone. For example, without being bound to any theory, analgesic effects of THC may be synergistically boosted by various terpenoids, anticonvulsant effects of CBD and THCV may be synergistically boosted by linalool, anti-inflammatory/antifungal effects of CBC and CBG may be synergistically boosted by caryophyllene oxide, anti-inflammatory/analgesic effects of CBC may be synergistically boosted by various terpenoids, sedative effects of CBN may be synergistically boosted by β-myrcene and nerolidol, to name just few examples of synergistic effects when phytocannabinoids and terpenoids are inhaled together as part of  cannabis  smoke. 
     Naturally occurring therapeutic compounds in  cannabis , including phytocannabinoids and terpenoids, are synthesized in secretory cells inside glandular trichomes of  cannabis . In addition, different strains of  cannabis  produce and can be bred to produce varying amounts of certain compounds. For example, common “street”  cannabis  may have been bred such that relatively high amounts of THC are present to maximize the “high” of the person using the  cannabis  for recreational purposes. The same strain of “street”  cannabis , however, may not have been bred to maximize, and therefore contain less than desired amounts of terpenoids or phytocannabinoids other than THC. As a result, while the effect of such  cannabis  strain as a euphoriant may be relatively high, their therapeutic effects may be relatively low. Therefore, to improve the therapeutic effects and to target certain therapeutic effects from  cannabis , attempts to cultivate different strains of  cannabis  having particular combinations and amounts of specific phytocannabinoids and terpenoids have been made. However, such effort has been time consuming and not necessarily aimed at mass cultivation to serve the general public. 
     While some terpenoids naturally occur in  cannabis , terpenoids also naturally occur in plants other than  cannabis . As with  cannabis , terpenoids in some plants give rise to the distinctive odor of the plants. For example, d-limonene occurs naturally in citrus plants, and is the predominant compound that gives rise to the familiar scent of citrus. Similarly, α-pinene occurs naturally in coniferous plants and is the predominant compound that gives rise to the familiar scent of pine. Thus, some terpenoids, such as d-limonene and α-pinene, occur relatively abundantly. 
     It has been found that the therapeutic effects of smoking herbs may be tailored by varying the terpenoid composition of the smoking herbs. In some embodiments the smoking herb may be  cannabis  and the therapeutic effects may include synergistic effects between the phytocannabinoids that are naturally present in a particular strain of  cannabis  and terpenoids that may be isolated from plants other than the particular strain of  cannabis  or other than  cannabis  in general. The terpenoids may be added to a preparation made from the particular strain of  cannabis  and may provide a terpenoid concentration that is just as high, if not higher, than terpenoid levels that are naturally occurring in, for example, other  cannabis  strains. Thus, in some embodiments, the terpenoid added to the smoking herb preparation may be at a higher concentration than that naturally found in the smoking herb or the terpenoid may not be naturally produced by the smoking herb plant at all. 
     It will be appreciated that adding desired types and amounts of terpenoids from plants other than the particular strain  cannabis  can offer several advantages. For example, terpenoids from other plants can be economically favorable compared to, for example, breeding particular strains of  cannabis  having similar types and amounts of terpenoids. In addition, the desired types and amounts can be targeted more specifically to enhance or magnify known therapeutic effects, or even create new therapeutic effects that may not be possible using natural or engineered strains of  cannabis  alone. 
     Reference will now be made to the drawings, in which like numerals refer to like parts throughout. 
       FIG. 1  is a flow chart illustrating a method  10  of preparing an herbal smoking blend, according to some embodiments. The method of preparing an herbal smoking blend comprises providing  20  a smoking herb preparation. The method additionally includes providing  30  a terpenoid solution comprising a terpenoid. The method further includes adding  40  the terpenoid solution to the smoking herb preparation. 
     In some embodiments, providing  20  the smoking herb preparation includes providing a smoking herb including smoking  cannabis , including any species, subspecies, strain or variety of  cannabis . The herb preparation can include any part of the plant of the  cannabis , including the leaf, the root, the stem, the flower, or any other part of the plant that occurs naturally. In some embodiments, the smoking herb includes  cannabis  plants cultivated for fiber and seed production, sometimes described as low-intoxicant, non-drug, or fiber types. In some other embodiments, the smoking herb includes  cannabis  plants cultivated for drug production, sometimes described as high-intoxicant or drug types. In some other embodiments, the smoking herb includes  cannabis  plants that are escaped, hybridized, or wild forms of either of the above types. 
     In some embodiments, a preparation includes smoking herb that has been sufficiently dried so that it can be combusted under ordinary ambient conditions, such that the resulting smoke can be inhaled. In some embodiments, a preparation includes a smoking herb and a rolling paper that can be used to roll the smoking herb into a thin cylinder using a rolling paper, similar to a cigarette. 
     In other embodiments, providing  20  the smoking herb preparation can include providing a smoking herb other than  cannabis . Examples of other smoking herbs include  amaranthus dubius, arctostaphylos uva - ursi, argemone mexicana, arnica, artemisia vulgaris, calea zacatechichi, canavalia maritima, cecropia mexicana, cestrum nocturnum, cynoglossum virginianum, cytisus scoparius, entada rheedii, eschscholzia californica, fittonia albivenis, hippobroma longiflora, humulus japonica, humulus lupulus, lactuca virosa, laggera alata, leonotis leonurus, leonurus cardiaca, leonurus sibiricus, lobelia cardinalis, lobelia inflata, lobelia siphilitica, nepeta cataria, nicotiana  (i.e., tobacco),  nymphaea alba, opium poppy, passiflora incarnata, pedicularis densiflora, pedicularis groenlandica, salvia divinorum, salvia dorrii, salvia, scutellaria galericulata, scutellaria lateriflora, scutellaria nana, scutellaria, sida acuta, sida rhombifolia, silene capensis, syzygium aromaticum, tagetes lucida, tarchonanthus camphoratus, turnera diffusa, verbascum , and  zornia latifolia , to name a few. 
     In some embodiments, providing  20  the smoking herb preparation comprises providing a smoking herb comprising at least one phytocannabinoid, such as a phytocannabinoid selected from the group consisting of delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC), cannabigerol (CBG), tetrahydrocannabivarin (THCV), cannabidivarin (SBDV) and cannabinol (CBN). 
     In some embodiments, providing  20  the smoking herb preparation comprises providing a smoking herb other than  cannabis . In some embodiments, for example where a synergistic effect between a phytocannabinoid and terpenoids is desired, the smoking herb other than  cannabis  may comprise at least one added phytocannabinoid, such as a phytocannabinoid selected from the group consisting of delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC), cannabigerol (CBG), tetrandrocannabivarin (THCV), cannabidivarin (SBDV) and cannabinol (CBN). 
     Still referring to  FIG. 1  the illustrated method of method  10  of preparing an herbal smoking blend additionally includes providing  30  a terpenoid solution comprising a terpenoid. As used herein, a terpenoid solution refers to a mixture comprising a terpenoid and a solvent, where at least a portion of the terpenoid is incorporated in the mixture to form the terpenoid solution. The terpenoid can be miscible, immiscible, or partially miscible in the solvent. In embodiments where the terpenoid is at least partially immiscible, the resulting mixture is sometimes referred to as an emulsion. 
     In some embodiments, providing  30  the terpenoid solution includes providing a solution including a terpenoid selected from the group consisting of d-limonene, α-pinene, β-myrcene, linalool, pulegone, 1,8-cineole (eucalyptol), α-terpineol, terpineol-4-ol, p-cymene, borneol, Δ-3-carene, β-caryophyllene, caryophyllene oxide, nerolidol, phytol, Eugenol, Sabinene, Linalyl Acetate, Camphor, Chamazulene, beta-Farnesene, alpha-Humulene, Benzyl Benzoate, Benzyl Acetate, Geraniol, Geranyl Acetate, gamma-Terpinene, beta-Pinene, and combinations thereof. 
     In some embodiments, providing  30  the terpenoid solution comprises providing a terpenoid and a solvent, and mixing the terpenoid and the solvent. The solvent can include any liquid, e.g., a volatile liquid, which can incorporate a desired amount of the terpenoid in the terpenoid solution. As used herein, a liquid that incorporates the terpenoid includes a liquid that can hold the terpenoid in either dissolved form or undissolved form (e.g., suspended in the form of an emulsion). In some embodiments, a terpenoid solution having a terpenoid incorporated therein can be a solution having at least 0.1% terpenoid by volume at room temperature and atmospheric pressure. 
     In some embodiments, the solvent comprises an alcohol, e.g., ethanol, and water. In some embodiments, the terpenoid solution comprises about 1% to about 5% by volume of the terpenoid, about 40% to about 90% by volume of ethanol and about 10% to about 55% by volume of water. In some embodiments, the terpenoid solution comprises about 2% to about 4% by volume of the terpenoid, about 66% to about 80% by volume of ethanol and about 20% to about 30% by volume of water. Advantageously, such a solution can allow the terpenoid to be evenly distributed or suspended in the solvent, thereby facilitating the formation of a homogenous solution that allows a desire quantity of terpenoid to be added to a smoking herb preparation. 
     Still referring to  FIG. 1 , in some embodiments, the terpenoid in the terpenoid solution can be in a substantially purified form including a targeted terpenoid selected from the group consisting of d-limonene, α-pinene, β-myrcene, linalool, pulegone, 1,8-cineole (eucalyptol), α-terpineol, terpineol-4-ol, p-cymene, borneol, Δ-3-carene, β-caryophyllene, caryophyllene oxide, nerolidol, phytol, and combinations thereof. As used herein, a substantially purified terpenoid refers to the terpenoid being free of impurities other than the targeted terpenoids, with a volume percent of the impurities not exceeding about 5%, about 1%, or about 0.1%. For example, if a substantially pure terpenoid includes a first terpenoid (e.g., d-limonene) and a second terpenoid (e.g. α-pinene) as targeted terpenoids, any other substance including other terpenoids (e.g., β-myrcene, linalool, etc.) would be considered impurities. 
     As described above, terpenoids can naturally originate from  cannabis  or other plants. In some embodiments, the terpenoid in the terpenoid solution does not naturally occur in the herb or herbs forming the smoking herb preparation. In some embodiments where the smoking herb preparation includes  cannabis , providing  30  the terpenoid solution includes providing a solution including a terpenoid that is derived from a plant other than  cannabis  in general. In some other embodiments where the smoking herb preparation includes  cannabis , providing  30  the terpenoid solution includes providing a solution including a terpenoid that is derived from a plant other than the  cannabis  strain from which the smoking herb has been prepared. 
     In some embodiments, the terpenoid in the terpenoid solution can be provided in the form of an essential oil. An essential oil, sometimes referred to as a volatile oil, an ethereal oil, or an athereola, refers to a concentrated liquid extracted from a plant that can contain, among other compounds, terpenoids. Compounds such as terpenoids included in essential oil often carry a distinctive scent, or essence (hence the name). 
     In some embodiments, the essential oils can be prepared using one of several methods including, without limitation, distillation, expression and solvent extraction, among others. In distillation, raw plant material, which can include the flowers, leaves, wood, bark, roots, seeds, and/or peel, is put into a distillation apparatus over water. The water is then heated above the boiling point to generate steam therefrom, which passes through the plant material. As the stem passes through the plant material, the volatile compounds are vaporized. The vapors may flow through a coil, where they condense back to liquid, which is then collected in a receiving vessel. In expression, the raw plant material is expressed mechanically or cold-pressed. Expression can be a suitable method where the raw material is available in relatively large quantities at relatively lower cost, such as orange peels for producing citrus-fruit oils. In solvent extraction, a solvent such as hexane or supercritical carbon dioxide is used to extract the oils. Solvent extraction can be a suitable method where the raw material is available in relatively small quantities at relatively higher cost, such as flowers. Solvent extraction can also be a suitable method where the chemical components are too delicate and easily denatured by the high heat used in steam distillation.

In some embodiments, the essential oil mixture consists essentially of  Salvia Sclarea  and  Pimenta Racemosa . In some of other embodiments, the essential oil mixture consists essentially of  Salvia Sclarea  and  Pistacia Lentiscus . In yet other embodiments, the essential oil mixture consists essentially of  Pistacia Lentiscus  and  Citrus Limonum.    
     In some other embodiments, the essential oil mixture comprises first and second essential oils extracted from the group of plants consisting of  Salvia Sclarea, Pimenta Racemosa, Pistacia Lentiscus , or  Citrus Limonum , wherein a volume ratio between first and second essential oils is between about 0.01:1 and about 1:1. In some other embodiments, the volume ratio is between about 0.10:1 and about 1:1, or between about 0.50:1 and about 1:1, for instance about 1:1. 
     Still referring to  FIG. 1 , the illustrated method  10  of preparing an herbal smoking blend further includes adding  40  the terpenoid solution to the smoking herb preparation. The terpenoid solution can be added using a suitable method for incorporating at least a portion of the terpenoid in the terpenoid solution into the smoking herb preparation. 
     In some embodiments, adding  40  the terpenoid solution comprises dropping the terpenoid solution on the smoking herb. As used herein, adding the terpenoid solution by dropping refers to delivering a volume of liquid using, for example, a dropper, to deliver the liquid. In some embodiments, the dropper may deliver the liquid in an amount of between about 5-100 drops per mL, depending on, among other things, the viscosity of the terpenoid solution and the type of dropper used. 
     In other embodiments, adding  40  the terpenoid solution comprises spraying a mist (or droplets) of the terpenoid solution on the smoking herb. As used herein, adding the terpenoid solution by spraying refers to delivering fine drops of the terpenoid solution dispersed in a gas by using, for example, a spray nozzle or atomizer, to deliver the terpenoid solution. The spray characteristics, including the spray pattern, the spray capacity, and the spray drop size depend on, among other things, the viscosity of the terpenoid solution and the type of spray nozzle used. In yet other embodiments, adding the terpenoid solution comprises spraying using an aerosol spray which includes the terpenoid solution. 
     In some embodiments, adding  40  the terpenoid solution comprises dipping, or at least partially immersing the smoking herb into the terpenoid solution. By way of an example, the smoking herb can be placed in a dip net or a similar device and lowered into a container containing the terpenoid solution. In some embodiments, a soaking time can be tailored to control the amount of terpenoid solution that is absorbed, impregnated, or incorporated into the smoking herb. In some embodiments, the soaking time is between about 1 second and about 1 day, or between about 10 seconds and about 1 hour, or between about 1 minute and about 10 minutes. The smoking herb can be subsequently dried in air, or by heating the smoking herb, for example at a temperature below a temperature at which the smoking herb ignites. 
     In some other embodiments, the smoking herb preparation comprises a smoking herb and a rolling paper. In these embodiments, adding  40  the terpenoid solution comprises adding the terpenoid solution to the rolling paper, which can subsequently be used to roll the smoking herb. The terpenoid can be added to the rolling paper using a suitable method to impregnate the rolling paper with the terpenoid solution. For example, the rolling paper can be dipped in a bath of terpenoid solution. Other methods include dropping or spraying the terpenoid solution on the rolling paper. For example, in some embodiments, the terpenoid can be added to a pre-rolled cigarette containing smoking herbs. 
     It will also be appreciated that the terpenoid solution can be added to the smoking herb by more than one method, for example, by two or more of the methods disclosed herein. For example, the terpenoid solution can be added to the smoking herb by dipping and drying the smoking herb preparation, and subsequently by providing drops of the terpenoid solution to the smoking herb or rolling paper for the smoking herb. In some embodiments, this can increase the concentrations of terpenoids (e.g., volatile terpenoids) in the preparation. In some other embodiments, different terpenoids solutions are added to the smoking herb preparation at different times. For example, a solution with relatively less volatile terpenoids may be added to the smoking herb concentration initially (e.g., hours before consumption, or from a manufacturer or supplier) and a solution with relatively more volatile terpenoids may be added to the smoking herb preparation immediately (e.g., minutes) before smoking. 
     In some embodiments where the smoking herb preparation includes  cannabis , the amount of terpenoid added to the smoking herb preparation exceeds the amount of  cannabis  terpenoid that was present in the smoking herb prior to adding the terpenoid solution to the smoking herb preparation. In some embodiments, the amount of terpenoid added to the smoking herb preparation exceeds the amount of  cannabis  terpenoid that was present in the smoking herb prior to adding the terpenoid solution to the smoking herb preparation, such that the overall amount of terpenoid increases by more than about 50%, by about 100%, or by about 1000%. 
     In some embodiments, the amount of added terpenoid exceeds about 0.001% by weight of the smoking blend, about 0.01% by weight of the smoking blend, or about 0.05% by weight. 
     In some embodiments, the method  10  of preparing an herbal smoking blend further comprises subjecting the smoking herb preparation to a drying process after adding the terpenoid solution.
