IN SINTESI

La piperina e’ un alcaloide derivante dal pepe nero (Piper Nigrum).

Diversi studi definiscono come, questa sostanza, sia in grado di apportare numerosi benefici nel nostro organismo.

La piperina oltre ad essere un inibitore tumorale (pubblicazione del 2008 in “Clinical Laboratory Science”) e un aiuto per l’ assorbimento di nutrienti importanti per il nostro regolare  funzionamento (articolo pubblicato nel 2010 in “Journal af Ayruvedas and Integrative Medicine”), ha una attività antidepressiva, in quanto incrementa la neurotrasmissione di serotonina e dopamina (studio pubblicato in “Pharmacology, Biochemestry and Behavior” nel 2009).

Ad attirare la nostra attenzione però sono stati gli studi condotti da J. E .Rose, professore accademico universitario, americano, inventore e ricercatore nel campo della nicotina e della cessazione del fumo, e dal suo collega F. M. Behm, che hanno accertato come, l’inalazione dell’ estratto di pepe nero, oltre a benefici a livello del sistema nervoso, modulando specifiche regioni del cervello, abbia anche delle utilità nel trattamento per smettere di fumare.

Gli studi sono stati effettuati su un campione di 48 fumatori, in seguito alla privazione dal fumo per una notte intera.

I soggetti sono stati sottoposti casualmente a  queste 3 diverse situazioni: un gruppo di fumatori sono stati esposti ad un espositivo che emanava vapore di olio essenziale di pepe nero, un secondo gruppo ad un dispositivo con una cartuccia di menta/mentolo, ed un terzo gruppo ad un dispositivo contenente una cartuccia vuota.

Durante la sessione era vietato fumare e i soggetti hanno inalato da dispositivi a piacere.

E’ stato riscontrato che la voglia di fumare era significativamente ridotto nella situazione con il pepe nero. Questi risultati permettono di sostenere l’opinione secondo la quale, le sensazioni del tratto respiratorio sono importanti per alleviare i sintomi di astinenza da fumo.

Anche altri studi globali sono stati condotti al fine di scoprire potenziali agenti naturali che possono essere utilizzati per smettere di fumare.

Tra queste sostanze ritroviamo il vapore dell’ estratto di pepe nero il quale riduce la voglia di sigaretta.

LE RICERCHE DI BEHM E ROSE

Piperine, also known by its trademarked name, BioPerine, is an extract derived from black pepper, Piper Nigrum L, and long pepper, Piper longum L. Piperine is what gives peppers their spicy taste. This extract is marketed as a nutritional supplement and has been found to increase the absorption of a variety of nutrients. Though some of the benefits of piperine have yet to be firmly established, it may also have immune-suppressing, tumor-inhibiting and antidepressant effects. While piperine is probably safe to use, some concerns have been raised regarding its potentially dangerous, enhancing effect on certain drugs. As with starting any new treatments, consult your doctor first.

Absorption of Nutrients

The most established effect of piperine is its effect on absorption of nutrients from the intestine. This effect is known as "bioenhancement." According to an article published in the "Journal of Ayruveda and Integrative Medicine" in 2010, piperine has been shown to increase the absorption of vitamin C, selenium, beta-carotene, vitamin A, vitamin B-6 and coenzyme Q. The article goes on to suggest that piperine may be useful for people who suffer from conditions that cause malabsorption of nutrients and people suffering from malnutrition.

Immunomodulator

While the primary immune system functions to eradicate foreign invaders, it can sometimes malfunction. A variety of diseases are caused by a faulty immune reaction. Piperine has been shown to decrease the activity of this inflammatory response. The findings from a study published in the "European Journal of Pharmacology" in 2010 suggest that piperine may decrease the communication of lymphocytes in the immune system, thereby slowing down their action. Piperine has been shown to be beneficial in gout, a disease characterized by a strong immune response against uric acid crystals. A study published in "Inflammation" in 2011 provided evidence that piperine blocked uric acid crystals from forming and that it could be used as a treatment for gout.

Anti-tumor Effect

Some evidence suggests that piperine may have some anti-cancer properties. A publication in "Clinical Laboratory Science" in 2008, for example, suggests that piperine inhibits the growth of colon cancers cells grown in a lab. The exact mechanisms by which the supplement prevents cancer are unknown, however, and whether this anti-cancer effect is effective outside of the laboratory remains to be proven.

Antidepressant

Piperine may have some antidepressant activity as well, though this has not yet been firmly established. A trial of piperine on rats found that the animals provided evidence that the supplement had antidepressant and cognitive-enhancing effects. These findings were published in "Food and Chemical Toxicology" in 2008. Another study published in "Pharmacology, Biochemistry and Behavior" in 2009 found that piperine increased the neurotransmission of serotonin and dopamine, two chemicals that are often deficient in depressed individuals. Clinical trials testing the supplement are needed to verify whether these benefits transfer to people.

Potential Side Effects

Although piperine is generally considered safe, important questions regarding its side effects and interactions remain to be answered. According to the "Journal of Food Safety," piperine is generally safe to consume as it does not cause any major alterations in blood tests. One potential adverse effect of piperine is that it may enhance the absorption of medical drugs, bringing them to dangerous levels in the blood stream. For this reason, the supplement should not be administered at the same time as any medications. Piperine may inhibit liver metabolism of drugs as well, which may also raise drug levels. Some animal tests with piperine suggest that it may have reproductive toxicity. Again, when starting any new treatments, consult your doctor first.

Antidepressant

Piperine may have some antidepressant activity as well, though this has not yet been firmly established. A trial of piperine on rats found that the animals provided evidence that the supplement had antidepressant and cognitive-enhancing effects. These findings were published in "Food and Chemical Toxicology" in 2008.

Abstract

Previous studies have suggested that sensory cues associated with cigarette smoking can suppress certain smoking withdrawal symptoms, including craving for cigarettes. In this study we investigated the subjective effects of a cigarette substitute delivering a vapor of black pepper essential oil. Forty-eight cigarette smokers participated in a 3-h session conducted after overnight deprivation from smoking. Subjects were randomly assigned to one of three conditions: one group of smokers puffed on a device that delivered a vapor from essential oil of black pepper; a second group puffed on the device with a mint/menthol cartridge, and a third group used a device containing an empty cartridge. Subjects puffed and inhaled ad libitum from the device throughout the session during which no smoking was allowed. Reported craving for cigarettes was significantly reduced in the pepper condition relative to each of the two control conditions. In addition, negative affect and somatic symptoms of anxiety were alleviated in the pepper condition relative to the unflavored placebo. The intensity of sensations in the chest was also significantly higher for the pepper condition. These results support the view that respiratory tract sensations are important in alleviating smoking withdrawal symptoms. Cigarette substitutes delivering pepper constituents may prove useful in smoking cessation treatment.

Abstract

Background: Cigarettes are considered as most addictive product and many people who quit smoking relapse within days. Today the use of tobacco is a greatest preventable cause of death in the world. Several pharmacological interventions are licensed for smoking cessation but other than this there are natural agents which could be very effective in smoking cessation.

Purpose of study: The present study is carried out to find out potential natural agents that could be used for smoking cessation and their mode of action in quitting smoking. Methodology: An electronic database search was performed in Embase, Medline and other search engines. Different articles were identified and their abstracts and full texts were assessed in the final review.

Results: After a comprehensive research it was found that the natural agents which can be used to stop smoking include fresh lime, black pepper, water, ginger, grape juice, St. John wort, ginseng, calamus, vitamin and antioxidants. Lime basically helps in alkalinizing the tissues which are normally more acidic in tobacco users. The vapours of black pepper oil reduce the craving for cigarettes. St. John’s wort is known to have antidepressant potential and helps in smoking cessation. Calamus removes the residual toxins in the lungs from cigarette smoking thus helps in quitting smoking. Consuming more vitamin C when a person is trying to drop off cigarettes prove to be effective in smoking cessation. Antioxidants decrease nicotine craving in those who are trying to quit smoking without making use of nicotine replacement therapy (NRT).

Conclusion: Overall this study shows that natural agents are effective and affordable, thus in combination with a behavioral support, these agents can be very helpful in quitting smoking.

Black pepper in smoking cessation

The effectiveness of black pepper in smoking cessation has been approved by various studies around the world. A study was conducted by Jed E. Rose in which forty-eight smokers participated and results show that craving for cigarettes was significantly reduced in respondents who puffed black pepper vapours of essential oil and this
