The Medicinal Health Benefits of Tongkat Ali (Eurycoma Longifolia)
1. Aphrodisiac and Sexual Health: Tongkat Ali is perhaps most famous for its reputation as a natural aphrodisiac. It is believed to enhance libido and sexual performance. Research suggests that Tongkat Ali may have a positive impact on testosterone levels, which can play a crucial role in maintaining sexual health.
For example, a study published in the Journal of Ethnopharmacology in 2013 found that Tongkat Ali supplementation significantly improved male sexual health parameters, including semen quality and erectile function.
2. Stress Reduction and Cortisol Regulation: This plant has been investigated for its potential to help manage stress and regulate cortisol, a hormone released in response to stress. High cortisol levels over extended periods can have detrimental effects on overall health. Tongkat Ali may help in reducing stress and improving mood.
A study published in the Journal of the International Society of Sports Nutrition in 2013 demonstrated that Tongkat Ali supplementation reduced cortisol levels and perceived stress in moderately stressed individuals.
3. Physical Performance and Stamina: Tongkat Ali is believed to boost energy levels and physical stamina. By supporting healthy testosterone levels and reducing oxidative stress, it may contribute to improved exercise performance.
An animal study published in the Asian Journal of Andrology in 2010 showed that Tongkat Ali extract supplementation increased muscle strength and endurance in rats.
4. Antioxidant and Anti-Inflammatory Effects: The plant contains compounds with antioxidant and anti-inflammatory properties that can help protect cells from damage and reduce inflammation in the body. These properties are important for overall health and can contribute to disease prevention.
A study published in the Journal of Natural Products in 2016 highlighted the antioxidant and anti-inflammatory activities of Tongkat Ali’s bioactive compounds.
5. Bone Health Support: Some research suggests that Tongkat Ali might have positive effects on bone health. Animal studies have shown that Tongkat Ali extract can increase bone formation and improve bone strength.
A study published in the Journal of Ethnopharmacology in 2011 found that Tongkat Ali extract helped prevent bone loss in orchidectomized rats (rats with surgically removed testes, resulting in reduced testosterone levels).
6. Cognitive Function Enhancement: Emerging research suggests that Tongkat Ali might have cognitive-enhancing properties. Compounds in Tongkat Ali could potentially support brain health and cognitive function.
A study published in the Journal of Alzheimer’s Disease in 2016 demonstrated that Tongkat Ali extract had neuroprotective effects and improved cognitive function in rats.
7. Anti-Diabetic Effects: Some studies indicate that Tongkat Ali might play a role in managing blood sugar levels and improving insulin sensitivity.
A study published in the journal Phytotherapy Research in 2014 showed that Tongkat Ali extract supplementation improved glycemic control in diabetic rats.

The Methods of Usage to Achieve the Provided Health Benefits of Tongkat Ali (Eurycoma Longifolia)
Here are some guidelines for using Tongkat Ali to attain its various medicinal properties:
1. Aphrodisiac and Sexual Health: To support sexual health and enhance libido, Tongkat Ali supplements are commonly used. Look for standardized extracts with a specified concentration of bioactive compounds like eurycomanone.
The typical dosage ranges from 200 to 400 mg of a 100:1 extract (equivalent to 20,000 to 40,000 mg of raw herb). It’s advisable to start with a lower dose and gradually increase it if needed. For optimal results, take Tongkat Ali consistently over a period of weeks.
2. Stress Reduction and Cortisol Regulation: Tongkat Ali can help manage stress and cortisol levels. A common dosage range for this purpose is similar to that for sexual health—around 200 to 400 mg of a standardized extract daily. Consistent use is important to experience its stress-reducing effects over time.
3. Physical Performance and Stamina: To enhance physical performance and stamina, Tongkat Ali extracts can be taken before exercise. A dosage of 200 to 400 mg before workouts may be effective. Keep in mind that individual responses can vary, so you may need to adjust the timing and dosage based on your body’s response.
4. Antioxidant and Anti-Inflammatory Effects: For antioxidant and anti-inflammatory benefits, Tongkat Ali extracts with standardized levels of active compounds can be consumed. A similar dosage range of 200 to 400 mg per day may be suitable. These benefits are more long-term in nature, so consistent use is key.
5. Bone Health Support: If you’re interested in supporting bone health, consider Tongkat Ali extracts with a focus on bioactive compounds related to bone health. Dosages similar to those mentioned above may be appropriate. Again, consistency is important for sustained benefits.
6. Cognitive Function Enhancement: To potentially enhance cognitive function, Tongkat Ali extracts could be consumed. The dosage range might be similar to the others—around 200 to 400 mg per day. Cognitive benefits, like other effects, may take time to become noticeable.
7. Anti-Diabetic Effects: If you’re looking to manage blood sugar levels, Tongkat Ali extracts could be considered. Dosages in the range of 200 to 400 mg per day might be beneficial. As always, monitor your blood sugar levels and consult with a healthcare professional, especially if you’re diabetic or on medication.
The Side Effects of Using Tongkat Ali Medicinal Plant
Here are some possible side effects and considerations to be aware of:
1. Hormonal Effects: Tongkat Ali is known for its potential to influence testosterone levels. While this can be beneficial for some individuals, excessive or prolonged use at very high doses could potentially lead to imbalances in hormone levels. This could manifest as symptoms like mood changes, irritability, acne, and changes in libido.
2. Agitation and Insomnia: Some users have reported experiencing increased energy levels and restlessness, which could lead to difficulty sleeping, especially if Tongkat Ali is taken too close to bedtime.
3. Digestive Distress: In some cases, gastrointestinal discomfort, including nausea, stomach ache, and diarrhea, has been reported.
4. Allergic Reactions: Allergic reactions are possible with any herbal supplement. If you are allergic to any plants in the Simaroubaceae family (e.g., quassia) or other related species, you may be at a higher risk of developing an allergic reaction to Tongkat Ali.
5. Interactions with Medications: Tongkat Ali may interact with certain medications, especially those that affect hormone levels, blood sugar, or blood pressure. It’s important to consult a healthcare professional if you’re taking medications before using Tongkat Ali.
6. Liver Health: There have been rare reports of liver toxicity associated with high doses of Tongkat Ali. While such instances are uncommon, it’s still crucial to monitor liver function if you’re using Tongkat Ali for an extended period.
7. Dosage-Dependent: Many of these side effects are often dose-dependent. Moderate use within recommended dosage ranges may minimize the risk of experiencing adverse effects.
