Massularia acuminata

Massularia acuminata is a Nigerian plant traditionally used as a chewing stick (for oral health) and aphrodisiac in Yoruba medicine. Preliminary rat studies suggest testosterone and libido increases, but HIGHER DOSES SHOWED LIVER TOXICITY. NO GRADED OUTCOMES - only animal research exists. The anti-gingivitis/oral health use is traditional but not rigorously validated. Cannot recommend use due to lack of human evidence and hepatotoxicity concerns at higher doses in animals.

Quick Answer

What it is

Massularia acuminata is a Nigerian plant traditionally used as a chewing stick (for oral health) and aphrodisiac in Yoruba medicine. Preliminary rat studies suggest testosterone and libido increases, but HIGHER DOSES SHOWED LIVER TOXICITY.

Key findings

  • Grade D: Testosterone
  • Grade D: Libido
  • Grade D: Liver Enzyme Levels

Safety

  • Preliminary rat studies suggest testosterone and libido increases, but HIGHER DOSES SHOWED LIVER TOXICITY.
  • No human studies exist, and higher doses (1000 mg/kg) caused liver toxicity in the same animal models, suggesting a narrow therapeutic window.
  • This adverse effect represents a serious safety concern and narrows the potential therapeutic window considerably.

Detailed Outcomes

D
Testosterone
In rat studies, Massularia acuminata aqueous extract at lower doses (50 mg/kg) increased serum testosterone levels. No human studies exist, and higher doses (1000 mg/kg) caused liver toxicity in the same animal models, suggesting a narrow therapeutic window.

moderate↑Improves
D
Libido
Rat studies observed increased sexual behavior and libido-related endpoints following administration of Massularia acuminata extract at lower doses. These findings have not been replicated in humans and must be interpreted cautiously given concurrent hepatotoxicity findings at higher doses.

D
Liver Enzyme Levels
In rat studies, Massularia acuminata at higher doses (1000 mg/kg) produced significant hepatotoxicity with elevated liver enzymes, indicating dose-dependent liver damage. This adverse effect represents a serious safety concern and narrows the potential therapeutic window considerably.

D
Gingival Health
A small RCT in 60 Nigerian schoolchildren compared Massularia acuminata chewing sticks to toothbrushes over six weeks. Slight improvements in gingival health were observed in the chewing stick group, but differences were not statistically significant.

Chromium

Chromium is a mineral that occurs naturally in the earth’s crust and is found in small amounts in a variety of foods. Chromium supplementation seems to enhance the effects of insulin in the body, leading to improvements in insulin sensitivity and blood sugar regulation in people with insulin resistance. Although chromium has historically been considered an essential nutrient for the human body, current evidence challenges this notion.

Panax ginseng is commonly referred to as “Korean ginseng”. It appears to be effective for mood, immunity, and cognition, but is subpar for erectile function, testosterone, and exercise performance.

DHEA

2 shared outcomes · 202 outcomes

DHEA is a steroid hormone produced by the adrenal glands. It’s a precursor to (i.e., is made into) estrogen and testosterone, and can exert weak benefits on its own. As an “antiaging” or performance enhancing supplement, its benefits are inconsistent.

Rhodiola Rosea

Rhodiola rosea, often called “rhodiola” for short, is a plant in the genus Rhodiola that’s used as an herbal supplement with adaptogenic properties that help to provide general resistance to stress. Although its mechanisms of action are not completely understood, it is clear that rhodiola increases resilience to stress at both the cellular and systemic levels.

Tongkat Ali

Tongkat Ali is a Southeast Asian herb traditionally used as an aphrodisiac and adaptogen. B-grade evidence for erectile function (small effect). C-grade evidence for cortisol reduction. IMPORTANT: Despite heavy marketing as a 'testosterone booster', evidence for testosterone increases in healthy men with normal testosterone is weak and inconsistent. Effects on testosterone appear limited to men with clinically low levels. Most studies have small sample sizes and methodological limitations. May have genuine adaptogenic effects on stress/cortisol.

Tribulus Terrestris

Tribulus terrestris is a plant whose root and fruits are used in Ayurvedic medicine for male virility and general vitality, respectively. It is also used in Traditional Chinese Medicine. It appears to reduce symptoms of sexual dysfunction (but not improve testosterone levels) in men and women and might improve metabolic health as well.
