Tongkat Ali

What is Tongkat Ali

Other Names: Eurycoma longifolia, Longjack

Tongkat Ali is a tree native to Malaysia, Thailand, and Indonesia. The part of the tree used medicinally is the root.

Why Do People Use Tongkat Ali?

Tongkat Ali was dubbed the "Asian Viagra" in a May 1999 report in the New Sunday Times.

It has been used in Malaysia for many years by men to increase sexual desire, libido, sexual performance and to treat erectile dysfunction.

Tongkat ali appears to work by increasing levels of the hormone testosterone. Testosterone is primarily responsible for the growth and development of male reproductive organs, including the penis, testicles, scrotum, prostate, and seminal vesicles. Normal testosterone levels maintain energy level, mood, fertility, and sexual desire.

Because of its testosterone-enhancing properties, tongkat ali is also used by bodybuilders to increase muscle mass and strength.

Safety

Reported side effects include insomnia, anxiety, and restlessness.

Tongkat ali should not be used by pregnant or nursing women or children.

Because tongkat ali increases testosterone levels it should not be used by men with breast cancer or prostate cancer, diabetes mellitus, heart disease, kidney disease, liver disease, or sleep apnea.

Tongkat ali should not be used by people with weakened immune systems as some evidence suggests it may further weaken immune function.

Drug Interactions

Tongkat ali should not be used by people taking immunosuppressant drugs.

It is especially important to tell your doctor or pharmacist if you are taking insulin. Tongkat ali may decrease blood sugar levels.

Maca


What is Maca?

Maca (Lepidium meyenii) is a root plant consumed as a food and for medicinal purposes. Maca is also known as "Peruvian ginseng" (despite the fact that it is not a member of the ginseng family), because it is used as a folk remedy to increase stamina, energy, and sexual function. It is typically taken as a pill or liquid extract or as powdered maca root.
Long used to enhance energy and boost stamina, maca is often touted as an aphrodisiac and a natural means of improving sexual performance and fertility. Although few scientific studies have tested maca's medicinal effects, some research suggests that maca may offer certain health benefits.

Benefits of Maca
Proponents claim that maca may help with these health concerns:
Maca is also said to aid in the treatment of cancer.

The Science Behind Maca
Here's a look at the available research on maca and its potential health benefits:

1) Maca and Sexual Function
There is "limited evidence" for maca's effectiveness in improving sexual function in men and women, according to a 2010 report published in BMC Complementary and Alternative Medicine. The report's authors analyzed four clinical trials, two of which found that maca may have positive effects on sexual dysfunction or sexual desire in healthy menopausal women or healthy adult men. However, the other two trials found that maca failed to produce any positive effects on sexual function.
In a 2008 study from CNS Neuroscience & Therapeutics, researchers found that maca may help alleviate sexual dysfunction caused by use of selective-serotonin reuptake inhibitors (or SSRIs, a class of medications used in treatment of depression). The study involved 20 people with depression, all of whom were experiencing SSRI-induced sexual dysfunction. Results revealed that maca may also help improve libido.

2) Maca and Fertility
One small study looked at the effect of 4 months of treatment with maca tablets on semen quality in nine adult men. Treatment with maca resulted in increased semen volume, sperm count, and sperm motility. Serum levels of testosterone and estradiol were not affected.
There are different types of maca, including yellow, black, and red maca. Black maca appears to have the greatest effect on sperm count, followed by yellow maca, which has moderate effects.

3) Maca and Mood in Menopause
Maca may help ease anxiety and depression in postmenopausal women, according to a 2008 study from the journal Menopause. For the study, 14 postmenopausal women took 3.5 grams of powdered maca for six weeks and then took a matching placebo for another six weeks. Study results showed that maca helped reduce anxiety and depression, as well as improve sexual function.

4) Maca and Energy
Although preliminary findings from animal-based studies indicate that maca may help improve endurance, there is currently a lack of scientific support for the claim that maca can help boost energy and fight fatigue.

5) Maca and Cancer
To date, there is no evidence that maca can help treat cancer.

Side Effects of Maca
Little is known about the safety and side effects of short-term or long-term use of maca. In addition, it's not known whether maca may produce harmful effects when combined with other medicine.

Using Maca
Powdered maca root can be added to smoothies, juice, and shakes. Raw powdered maca root is available for people on a raw food diet. Maca is also available as a nutritional supplement, in liquid or pill form.


Should You Use Maca for Health Purposes?
Due to the lack of supporting research, it's too soon to recommend maca as a treatment for any health condition. If you're considering the use of maca, make sure to consult your physician before beginning treatment.


Guarana

What is guarana?

Other Names: Paullinia cupana, Brazilian cocoa

Guarana (pronounced gwa-ra-NAH) is a creeping shrub native to Venezuela and northern Brazil in the Amazon rain forest. The fruit are small, bright-red, and contains black seeds.

Guarana seeds are rich in caffeine and contain up to 4-8% caffeine, more than coffee beans, which contain approximately 1–2.5% caffeine. The seeds are also rich in tannins and xanthine alkaloids theophylline and theobromine.

Why do people use guarana?

Guaraná is reputed to be a stimulant and increase mental alertness, fight fatigue, and increase stamina and physical endurance.

Guarana drinks and sodas are very popular in Brazil (where guarana is considered to be a health tonic), almost as popular as cola-based sodas. Sweet, carbonated guarana drinks include the popular brands Guaraná Antarctica, Guaraná Brahma, and Kuat (from Coca-Cola Company).

In North America, guarana has recently become a popular ingredient in energy drinks and teas.

Guarana is one of the richest sources of caffeine, containing up to three times the amount of caffeine as coffee. Unlike coffee, the amount of caffeine doesn't have to be listed on guarana drinks.

In addition to its stimulant properties, guarana is also a popular ingredient in herbal weight loss pills. Some evidence indicates that guarana may suppress appetite and increase fat-burning.

What research has been done on guarana?


An animal study examined the effect of 14 days of guarana supplementation on fat metabolism in sedentary and trained rats and found that the guarana's fat-burning effect is due to the caffeine content. Decaffeinated guarana extracts had no effect on lipid metabolism.

A Journal of Psychopharmacology study found that guarana improved memory, mood and alertness at low (37.5 mg, 75 mg) vs. higher (150 mg, 300 mg) doses. However, another study examined the long-term use of guarana, caffeine, or placebo on the cognition of 45 older individuals. There were no significant effects of guarana on cognition.

Safety

Guarana should not be used by people who are sensitive to caffeine or xanthines.

People with heart conditions, diabetes, high blood pressure, epilepsy, overactive thyroid, anxiety, insomnia, and kidney disease should only use guarana under the supervision of their doctor.

The safety of guarana in pregnant or nursing women has not been established. Since many doctors recommend limiting caffeine during pregnancy and nursing, guarana should be avoided because caffeine content differs from product to product and it isn't possible for consumers to accurately estimate how much caffeine they are consuming through guarana.

Guarana should not be taken with any products containing ephedra. Serious adverse effects have been reported with this combination. It may increase the risk of stroke, hemorrhage, myocardial infarction, and sudden death and has been associated with increases in heart rate, blood pressure, and potentially harmful changes in glucose and potassium levels.

A report published in the Journal of Herbal Pharmacotherapy described the case of a heart rhythm abnormality called premature ventricular contraction associated with two herbal supplements that both contained large doses of guarana.

Initial symptoms of guarana overdose include difficulty urinating, vomiting, and abdominal cramps and spasms. If you suspect a guarana overdose, seek medical attention immediately.

Common Forms

Guarana can be found in powder or pill form. It is an ingredient in energy drinks, sodas, and other beverages.

Drug interaction

Guarana has been found to decrease platelet aggregation and thromboxane synthesis, so it may increase the risk of bleeding when taken with aspirin, anticoagulants such as Warfarin (Coumadin®), and platelet inhibitors such as Ticlopidine (Ticlid®), Clopidogrel (Plavix®).

Guarana should not be combined with MAO-inhibitors, and may cause headaches.
