Eurycoma Longifolia

Tongkat Ali

One of the most powerful and versatile herbs for both men and women

Tongkat Ali, often referred to as Long Jack, is a powerful herbal remedy derived from the roots of Eurycoma Longifolia, a shrubby tree native to rainforests of South East Asian countries such as Thailand, Vietnam and Malaysia. Tongkat Ali has been  utilized as conventional medicine for many years in these regions, and has now been expanding to areas all over the world for the astounding effects that have been presented. 

Although many online manufacturers promote Tongkat Ali as a sort of natural “Viagra”, there are more than one hundred research papers have been conducted and published on a wide range of health benefits from Tongkat Ali. Conventional Southeast Asian medicine uses Tongkat Ali to treat a variety of ailments including erectile dysfunction, fevers, bacterial infections, malaria, to reduce stress, increase energy, leukemia, diabetes and the list goes on. Decoctions of Tongkat Ali leaves are used for washing itches, while the fruits are used in curing dysentery. It’s bark has been documented as being used as a vermifuge to expel intestinal worms, while the taproots are used to treat high blood pressure. Although this Malaysian wonder is believed to be a multi- purpose phenomenon, it’s most touted aspect are it’s roots which are believed to posses effective and qualitative effects useful in the treatment of infertility and impotency for both men and women.

Tongkat Ali contains the presence of phenolic compounds, flavonoids, terpenoids, alkaloids, protein, quassinoids such as eurycolactone, eurycomaoside, and eurycomanone, and many other compounds that act as antioxidants. 

Testosterone booster for both men and women?

The benefits of Tongkat Ali potentially stem from different compounds present in the plant. These compounds include alkaloids, flavonoids, quassinoids, and various others . Although Long Jack contains an array of beneficial compounds, the quassinoids in it’s chemistry have been recognized as being the culprits behind it’s testosterone boosting effects. It’s a common belief amongst many people that testosterone is a masculine sex hormone and only  a masculine sex hormone.  The truth may come as a surprise to many but the reality is that both males and females produce testosterone, and testosterone is vital to both genders for lots of important reasons.     

The major sex hormones can be classified as estrogens or androgens. Both classes of hormones are present in males and females alike, but in vastly different amounts. Estrogens are more actively produced in the ovaries of women and androgens in the testes of men. The compounds eurycomanone and13-alpha (21) epoxy-eurycomanone derived from Tongkat Ali have been shown to boost testosterone levels by stimulating testosterone secretion in specific types of cells. Eurycomanone and13-alpha (21) epoxy-eurycomanone boost the production of the hormones leutinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are called gonadotropins. Gonadotropins are peptide hormones (hormones whose molecules are peptides or proteins) that regulate ovarian and testicular function and are essential for normal growth, sexual development and reproduction. Leutinizing hormone binds to receptors on Leydig cells in the testes and this  stimulates the synthesis and secretion of testosterone. As the components of Tongkat Ali boost LH production, LH boosts testosterone secretion.  In women, Theca cells in the ovary respond to LH stimulation by secretion of testosterone, which is converted into estrogen by adjacent granulosa cells. 

Clinical Studies

Eurycoma longifolia in managing idiopathic male infertility

A study conducted by the Department of Community Medicine, School of Medical Sciences at University Sains Malaysia, investigated the effects of treatment on infertility with a proprietary, standardized, water- soluble extract of root of Eurycoma Longifolia. A total of 350 patients were given 200 mg of Tongkat Ali extract daily, with follow up semen analyses  performed every 3 months for 9 months. Of those 350 patients, 75 of them completed one full cycle of 3 months. In the end, results of the semen analyses showed significant improvements in semen parameters all around. The proprietary extract significantly improved the sperm quality in these patients, allowing for 11 spontaneous pregnancies.

A randomized, double blind placebo controlled study  enrolled 93 participants aged 25-65 years of age to investigate the safety and efficacy of Eurycoma Longifolia in combination with multivitamins (EL+MV). The 24 weeks study had the intent of concluding the effects of Tongkat Ali extract verses a placebo on improving quality of life (QoL), mood and stress in moderately stressed healthy participants. The following were the primary methods used to measure the following; QoL measured by 12- Item Short Form Health Survey questionnaire (SF-12) and mood measured by Profiles of Mood Scores (POMS).  The second endpoint was stress measured  by Multi-Model Stress Questionnaire (MMSQ). The safety of the intervention product was measured by a complete metabolic panel, lipid and renal analysis including immune parameters. As a result, an increasing trend in POMS- vigour domain was observed in the EL+MV group at week 12. A 15% decrease in physical stress was also observed compared with a 0.7% decrease in the placebo group. When the subjects were sub grouped according to age, 25-45 and 46-65, between group significance was observed in the 25-45 year group in the social functioning domain of SF-12 and POMS vigour in the 46-65 age group. Regarding immune parameters, lymphocytes increased significantly in the active group. To sum it all up, researchers concluded that Tongkat Ali extract, when taken with a multivitamin, may support the quality of life , mood, stress and immune parameters in healthy individuals. 

Immunity and our immune system is undoubtedly an important aspect of our being. It seems that with certain global events or just mere curiosity, the topic of immunity happens to be gaining traction. The term antibodies gets dragged along with immunity quite a lot, but some would argue that more than antibodies, T cells play a more important role than antibodies during natural infection. Immunological studies have actually shown the importance of T cells in fighting viral infection, more than antibodies. A research study conducted by researchers in Japan concluded that a standardized Tongkat Ali extract potentially improved the immune response of the subjects. In this randomized double-blind placebo controlled parallel study, eighty-three middle aged citizens of Japan were administered with 200 mg/ day of Tongkat Ali extract or rice powder as a placebo for 4 weeks. Parameters such as immunological grade, immunological age and other immune parameters were measured. As a result of the study, at week 4, SIV and immunological grade were significantly higher in the Tongkat Ali subject group than the placebo. The numbers of total CD4 T cells, Naive T cells, Lymphocytes and other t cells were also significantly higher in the Tongkat group. No severe adverse effects were observed.
