Question: What stimulants are derived from plants that have proven popular?
About the article "Botany", section "Medicine and materials".

Candidate passages:
  Alcohol – Euphoria has been reported during the first 10–15 minutes of alcohol consumption  Passion Flower ("Passiflora incarnata") – Widely used as a sedative that has calming effects on the nervous system and acts as a sleep aid.
One harmala alkaloid present in this herb in the form of harmine is thought to induce meditative and euphoric effects.
Catnip – Contains a sedative known as nepetalactone that activates opioid receptors.
It elicits sniffing, licking, chewing, head shaking, rolling, and rubbing in cats, which are indicators of pleasure.
Catnip does not, however, induce the same response in human beings.
Cannabis – Tetrahydrocannabinol, the main psychoactive ingredient in the Cannabis plant has both stimulant and depressant properties but is commonly known to induce euphoria  Stimulants – Psychomotor stimulants are known to suppress locomotor activity (the subject becomes hypoactive) at therapeutic doses.
But are known to stimulate movement and hyperactivity in higher doses.
Euphoria can be produced by stimulants at any dose, but are more commonly seen when taken in higher doses.
Euphoria caused by stimulants is most often expressed by excessive talking, heighten levels of energy, and a reduced appetite (anorexia).
Amphetamines are the best known drugs in this category, which also include drugs like cocaine and methylphenidate.
MDMA – MDMA, also known as "ecstasy" and MDEA ("eve") are euphoriant drugs that induce "short-term feelings of euphoria, rushes of energy, and increased tactility" and are popular amongst young adults.
Opium – Opium and its derivatives morphine and codeine are drugs "derived from the unripe seedpods of the opium poppy produces drowsiness and euphoria and reduces pain"  Corticosteroids - Corticosteroids may produce a feeling of inappropriate well-being ("steroid euphoria") in some patients when taken for allergies and chronic obstructive lung disease.
Rome and Graceland have graded the psychiatric symptoms of corticosteroid excess, with mild euphoria in Grade 1, and heightened euphoria (effusive, expansive and hypomanic behavior) in Grade 2.  
 Alcohol: "Euphoria, the feeling of well-being, has been reported during the early (10–15 min) phase of alcohol consumption" (e.g., beer, wine or spirits) Passion Flower ("Passiflora incarnata") is widely used as a sedative that has calming effects on the nervous system and acts as a sleep aid.
One harmala alkaloid present in this herb in the form of harmine is thought to induce meditative and euphoric effects.
Catnip Catnip contains a sedative known as nepetalactone that activates opioid receptors.
In cats it elicits sniffing, licking, chewing, head shaking, rolling, and rubbing which are indicators of pleasure.
Catnip does not however, induce the same response in humans.
Cannabis Tetrahydrocannabinol, the main psychoactive ingredient in this plant can have sedative and euphoric properties.
Stimulants: "Psychomotor stimulants produce locomotor activity (the subject becomes hyperactive), euphoria, (often expressed by excessive talking and garrulous behaviour), and anorexia.
The amphetamines are the best known drugs in this category..." MDMA: The "euphoriant drugs such as MDMA (‘ecstasy’) and MDEA (‘eve’)" are popular amongst young adults.
MDMA "users experience short-term feelings of euphoria, rushes of energy and increased tactility."
Opium: This "drug derived from the unripe seed-pods of the opium poppy ... produces drowsiness and euphoria and reduces pain.
Morphine and codeine are opium derivatives."
Several species contain sapogenins.
They have been used traditionally as uterine stimulants, the inspiration for the common name birthwort.
In a 1918 publication, Joseph E. Meyer called it "beth root", probably a corruption of "birthroot".
He claimed that an astringent tonic derived from the root was useful in controlling bleeding and diarrhea. 
Leibenstein has used these 2 terms stimulants and shocks in his theory quite often.
He defines stimulant as any event that changes the value of a variable away from its equilibrium value so that due to this event there is an initial increase in the per capita income.
Shock on the other hand has been defined by Leibenstein as any event external to the system due to which per capita income is reduced initially.
Now in underdeveloped economies shocks are more powerful than stimulants so what should be done in such a scenario is that the levels of incomes should be risen to such an extent that stimulants become stronger than shocks and the growth in incomes becomes self-sustaining. 
Patients with Tourette syndrome who are referred to specialty clinics have a high rate of comorbid ADHD.
Patients who have ADHD along with tics or tic disorders may also have problems with disruptive behaviors, overall functioning, and cognitive function, accounted for by the comorbid ADHD.
The treatment of ADHD in the presence of tic disorders has long been a controversial topic.
Past medical practice held that stimulants (such as Ritalin) could not be used in the presence of tics, due to concern that their use might worsen tics; however, multiple lines of research have shown that stimulants can be cautiously used in the presence of tic disorders.
Several studies have shown that stimulants do not exacerbate tics any more than placebo does, and suggest that stimulants may even reduce tic severity.
Controversy remains, and the PDR continues to carry a warning that stimulants should not be used in the presence of tic disorders, so physicians may be reluctant to use them.
Others are comfortable using them and even advocate for a stimulant trial when ADHD co-occurs with tics, because the symptoms of ADHD can be more impairing than tics.
The stimulants are the first line of treatment for ADHD, with proven efficacy, but they do fail in up to 20% of cases, even in patients without tic disorders.
Current prescribed stimulant medications include: methylphenidate (brand names Ritalin, Metadate, Concerta), dextroamphetamine (Dexedrine), and mixed amphetamine salts (Adderall).
Other medications can be used when stimulants are not an option.
These include the alpha-2 agonists (clonidine and guanfacine), tricyclic antidepressants (desipramine and nortriptyline), and newer antidepressants (bupropion and venlafaxine.
There have been case reports of tics worsening with bupropion (brand name Wellbutrin).
There is good empirical evidence for short-term safety and efficacy for the use of desipramine, bupropion and atomoxetine (Strattera).
