Plant derived substances with anti-cancer activity: from folklore to practice.

“Plants have had an essential role in the folklore of ancient cultures. In addition to the use as food and spices, plants have also been utilized as medicines for over 5000 years.

It is estimated that 70-95% of the population in developing countries continues to use traditional medicines even today. A new trend, that involved the isolation of plant active compounds begun during the early nineteenth century.

This trend led to the discovery of different active compounds that are derived from plants.

In the last decades, more and more new materials derived from plants have been authorized and subscribed as medicines, including those with anti-cancer activity.

Cancer is among the leading causes of morbidity and mortality worldwide. The number of new cases is expected to rise by about 70% over the next two decades. Thus, there is a real need for new efficient anti-cancer drugs with reduced side effects, and plants are a promising source for such entities.

Here we focus on some plant-derived substances exhibiting anti-cancer and chemoprevention activity, their mode of action and bioavailability. These include paclitaxel, curcumin, and cannabinoids.

In addition, development and use of their synthetic analogs, and those of strigolactones, are discussed. Also discussed are commercial considerations and future prospects for development of plant derived substances with anti-cancer activity.”

The Genetic Structure of Marijuana and Hemp.

“Despite its cultivation as a source of food, fibre and medicine, and its global status as the most used illicit drug, the genus Cannabis has an inconclusive taxonomic organization and evolutionary history.

Drug types of Cannabis (marijuana), which contain high amounts of the psychoactivecannabinoid Δ9-tetrahydrocannabinol (THC), are used for medical purposes and as a recreational drug.

Hemp types are grown for the production of seed and fibre, and contain low amounts of THC.

Two species or gene pools (C. sativa and C. indica) are widely used in describing the pedigree or appearance of cultivated Cannabis plants.

Using 14,031 single-nucleotide polymorphisms (SNPs) genotyped in 81 marijuana and 43 hemp samples, we show that marijuana and hemp are significantly differentiated at a genome-wide level, demonstrating that the distinction between these populations is not limited to genes underlying THC production.

We find a moderate correlation between the genetic structure of marijuana strains and their reported C. sativa and C. indica ancestry and show that marijuana strain names often do not reflect a meaningful genetic identity.

We also provide evidence that hemp is genetically more similar to C. indica type marijuana than to C. sativa strains.”

Cannabidiol, a nonpsychoactive Cannabis constituent, protects against myocardial ischemic reperfusion injury

Heart and Circulatory Physiology

“CANNABINOIDS ARE NATURAL and synthetic compounds structurally or pharmacologically related to the constituents of the plant Cannabis sativa or to the endogenous agonists (endocannabinoids) of the cannabinoid CB1 and CB2 receptors.

Cannabidiol (CBD) is a major cannabinoid constituent of Cannabis.

In contrast to tetrahydrocannabinol, CBD binds very weakly to CB1 and CB2 receptors. Contrary to most cannabinoids, CBD does not induce psychoactive or cognitive effects.

CBD has been shown to have anti-inflammatory properties. CBD (together with tetrahydrocannabinol) has been successfully tested in a few preliminary human trials related to autoimmune diseases…

Cannabidiol (CBD) is a major, nonpsychoactive Cannabis constituent with anti-inflammatory activity mediated by enhancing adenosine signaling.

Inasmuch as adenosine receptors are promising pharmaceutical targets for ischemic heart diseases, we tested the effect of CBD on ischemic rat hearts.

Our study shows that CBD induces a substantial in vivo cardioprotective effect from ischemia that is not observed ex vivo.

Inasmuch as CBD has previously been administered to humans without causing side effects, it may represent a promising novel treatment for myocardial ischemia.”

The draft genome and transcriptome of Cannabis sativa

“Cannabis sativa has been cultivated throughout human history as a source of fiber, oil and food, and for its medicinal and intoxicating properties.

The availability of the Cannabis sativa genome enables the study of a multifunctional plant that occupies a unique role in human culture. Its availability will aid the development of therapeutic marijuana strains with tailored cannabinoid profiles and provide a basis for the breeding of hemp with improved agronomic characteristics.”

Hemp (Cannabis sativa L.) seed oil: Analytical and phytochemical characterization of unsaponifiable fraction.

“Non-drug varieties of Cannabis sativa L., collectively known as “hemp”, have been an important source of food, fiber and medicince for thousands of years. The ever-increasing demand for vegetables oils has made it essential to characterize additional vegetable oil through innovative uses of its components…

This study is an important contribution for Cannabis sativa L. valorization as a source of bioactive compounds contributing to research novel applications for hemp seed oil in the food, pharmaceutical, cosmetic and other non-food industries.”

Medical marijuana stopped girl’s seizures when nothing else would – msn

Photo of Charlotte Figi - Realm of Caring via Facebook

 

“Charlotte Figi had her first seizure in 2006, when she was 3 months old. Her parents, Matt and Paige Figi, had every test conducted, yet no cause could be found. Years passed, and the seizures continued. Charlotte took medications, but she stopped developing cognitively. She was finally diagnosed with a severe form of epilepsy, Dravet Syndrome. Matt discovered the case of a boy with Dravet who’d been helped by low-level THC medical marijuana. By that point, Charlotte couldn’t walk, talk or eat, and she was having up to 300 grand mal seizures a week.

Desperate to find a solution, Matt and Paige applied for a medical marijuana card, making Charlotte, then 5, the youngest applicant in Colorado. They gave her a small amount of cannabis oil. The seizures stopped. Now Charlotte takes the oil twice daily with food, has only a few seizures a week, and is walking, talking and riding her bike. “My thought now is why were we the ones that had to go out and find this cure? This natural cure?” says Matt. “How come [a doctor] didn’t make me aware of this?””

Most Docs OK With Medical Marijuana: Survey – US News and World Report

“Majority would give a prescription to an advanced cancer patient in pain. Three-quarters of doctors who responded to a survey about medical marijuana said they would approve the use of the drug to help ease pain in an older woman with advanced breast cancer.”

“The point of the vignette was to illustrate the kinds of patients that show up on our doorstep who need help. This issue is not one you can ignore, and some states have already taken matters into their own hands,” said Dr. J. Michael Bostwick, a professor of psychiatry at the Mayo Clinic in Rochester, Minn.

“There are no 100 percents in medicine. There’s a lot of anecdotal evidence that this is something we should study more. Forgive the pun, but there’s probably some fire where there’s smoke, and we should investigate the medicinal use of marijuana or its components,” Bostwick said.

Marijuana comes from the hemp plant Cannabis sativa. It’s a dry, shredded mix of the plant’s leaves, flowers, stems and seeds. It can be smoked as a cigarette or in a pipe, or it can be added to certain foods, such as brownies.”

Muscular Dystrophy-Cannabinoids-Symptom Relief

“Cannabinoids Help Muscular Dystrophy Symptoms: Cannabinoids are now known to have the capacity for neuromodulation, via direct, receptor-based mechanisms, at numerous levels within the nervous system. 

These provide therapeutic properties that may be applicable to the treatment of neurological disorders, including anti-oxidative, neuroprotective effects, analgesia, anti-inflammatory actions, immunomodulation, modulation of glial cells and tumor growth regulation. 

Beyond that, the cannabinoids have also been shown to be “remarkably safe with no potential for overdose.”

(vaporizing) Marijuana:

“miraculously improved his quality of life so much so that he left his family and friends in New Jersey to live in California, where he can readily get his medication.”

Sublingual (under the tongue)-tincture (alcohol based) or infused oil (olive or food grade glycerin or coconut)

Topicals (salves, ointments, balms) for muscle pain and spasms.

Cannabinoids:  increase appetite, analgesic (rid pain), muscle relaxant, saliva reduction, bronchodialation,  and sleep induction.

 

CBD-rich strains are best choice.  Sativa dominant x Indica.”

How many sites of action for endocannabinoids to control energy metabolism?

Abstract

“The promising results obtained by clinical trials using Rimonabant to tackle visceral obesity and related disorders recently promoted a remarkable impulse to carry out detailed investigations into the mechanisms of action of endocannabinoids in regulating food intake and energy metabolism. The endocannabinoid system has been known for many years to play an important role in the modulation of the neuronal pathways mediating the rewarding properties of food. However, in the last few years, with the advanced understanding of the crucial role of the hypothalamic neuronal network in the regulation of appetite, several studies have also directed attention to the orexigenic role of the endocannabinoid system, substantiating the well known appetite stimulating properties of derivatives of Cannabis sativa. Furthermore, the last 2 years have seen a number of relevant publications emphasizing the role of endocannabinoids as significant players in various peripheral metabolic processes. To date, the roles of the endocannabinoid system in influencing energy metabolism have proved to be more complex than was formerly believed. However, the diverse ability to modulate both central and peripheral processes highlights the pivotal involvement of the endocannabinoid system in the control of metabolic processes. This review describes the roles of endocannabinoids and the cannabinoid type 1 receptor (CB1) in the control of energy balance.”
