Brazilian Ginseng
Also known as: Brazilian Ginseng, Suma root, Para Ginseng, Pfaffia glomerata, Pfaffia paniculata
Overview
Brazilian Ginseng, scientifically known as *Pfaffia paniculata*, is a root extract from a plant native to South America, particularly Brazil. Unlike true ginseng species (*Panax*), it contains unique saponins called pfaffosides, which are believed to be responsible for its biological effects. It is primarily used as an adaptogenic herbal supplement, traditionally valued for its tonic properties. Its main applications include reducing fatigue, enhancing physical and mental performance, supporting the immune system, and aiding in metabolic regulation. While it shares some purported benefits with *Panax* ginseng, the research specifically on *Pfaffia paniculata* is moderate, with most clinical studies focusing on fatigue and metabolic effects. The evidence base is less robust compared to *Panax* ginseng, and high-quality randomized controlled trials (RCTs) specifically on Brazilian Ginseng are limited, often complicating direct conclusions when grouped with other ginseng types.
Benefits
Brazilian Ginseng is primarily investigated for its potential to reduce fatigue and improve glycemic control. While much of the strong evidence comes from studies on *Panax* ginseng, these benefits are often extrapolated to *Pfaffia paniculata* due to its adaptogenic classification. Meta-analyses on ginseng supplements, predominantly *Panax* species, indicate statistically significant reductions in disease-related fatigue, with moderate effect sizes (e.g., SMD ~ -0.5 to -0.7) over placebo in some RCTs. This suggests potential benefit for patients with conditions causing fatigue, such as cancer or chronic illness. For glycemic control, systematic reviews of *Panax* ginseng show modest reductions in fasting blood glucose (FBG) and HbA1c in diabetic patients, with greater effects observed in those with higher baseline glucose levels. Individuals with type 2 diabetes or impaired glucose tolerance may experience modest improvements. However, current evidence does not support significant benefits on plasma lipid levels. The effects, while statistically significant, are generally moderate, and clinical relevance depends on individual response and baseline severity. Most trials range from 4 to 12 weeks, with longer-term effects less studied.
How it works
The adaptogenic effects of Brazilian Ginseng are thought to involve the modulation of the hypothalamic-pituitary-adrenal (HPA) axis, which plays a crucial role in the body's stress response. Its active compounds, primarily pfaffosides (a type of saponin), are believed to contribute to its biological actions. These saponins may interact with steroid hormone receptors and modulate cytokine production, influencing the body's inflammatory and immune responses. Brazilian Ginseng also exhibits antioxidant activity, which helps protect cells from oxidative stress. Through these mechanisms, it influences energy metabolism, supports immune function, and contributes to neuroendocrine regulation. The absorption and bioavailability of pfaffosides can vary, and their metabolites may persist in the body for several weeks, potentially influencing the design and interpretation of clinical trials.
Side effects
Brazilian Ginseng is generally considered well-tolerated in clinical trials, with no serious adverse events consistently reported. Common side effects, though not consistently observed across all studies, may include mild gastrointestinal discomfort, headache, and insomnia. These are typically mild and transient. Allergic reactions are rare. There are no significant rare adverse effects documented. Caution is advised regarding potential drug interactions, particularly with anticoagulants due to a theoretical risk of increased bleeding, and with hypoglycemic agents, as it may enhance their blood glucose-lowering effects, potentially leading to hypoglycemia. Brazilian Ginseng is generally contraindicated during pregnancy and breastfeeding due to a lack of sufficient safety data. Individuals with autoimmune diseases are also often cautioned. Data on its use in children and the elderly are limited. Diabetic patients should closely monitor their blood glucose levels if taking Brazilian Ginseng, especially if also on diabetes medication.
Dosage
Specific dosage guidelines for Brazilian Ginseng are not as well-established as for *Panax* ginseng, and doses used in studies vary widely due to a lack of standardization. However, for ginseng supplements in general, studies often use 200–400 mg of standardized extract daily. For Brazilian Ginseng, doses up to 1,000 mg/day have been used in some contexts without serious adverse effects, but there is no established maximum safe dose. To observe potential benefits, consistent daily dosing for at least 4 weeks is generally recommended, with most trials ranging from 4 to 12 weeks. Extracts standardized to pfaffoside content are preferred to ensure consistency in active compounds. While not strictly required, consuming Brazilian Ginseng with a fatty meal may enhance the absorption of its saponins. No specific cofactors are identified as necessary for its efficacy.
FAQs
Is Brazilian Ginseng the same as Panax Ginseng?
No, Brazilian Ginseng (*Pfaffia paniculata*) is a distinct species from *Panax* ginseng, with different active compounds, although both are considered adaptogens.
How long does it take to see benefits?
Benefits typically become noticeable after 4 to 12 weeks of consistent daily supplementation.
Is it safe to take with diabetes medications?
Caution is advised; it may lower blood glucose, so monitor your blood sugar closely to avoid hypoglycemia if combining with diabetes medications.
Can it cause insomnia?
Mild insomnia has been reported in some cases, but it is an uncommon side effect.
Does it improve lipid profiles?
Current research does not support significant lipid-lowering effects from Brazilian Ginseng supplementation.

It also cautioned that lower-quality trials were more likely to report positive findings, suggesting a risk of bias in the overall literature.
- https://pureportal.coventry.ac.uk/files/31879702/Binder4.pdf – This meta-analysis investigated the effect of ginseng supplementation on blood lipid profiles. The findings indicated no significant effect on plasma lipid levels, suggesting that ginseng, including Brazilian Ginseng, is unlikely to provide benefits for lipid management.
