Black Nightshade Extract
Also known as: Black Nightshade, Makoi, Petit Morel, Solanum nigrum
Overview
*Solanum nigrum*, commonly known as Black Nightshade, is a plant native to Europe and Asia but now found worldwide. It has a history of use in traditional medicine for its purported therapeutic properties. The plant contains various bioactive compounds, including alkaloids, flavonoids, steroids, glycoproteins, tannins, polysaccharides, and polyphenolic compounds, which are believed to contribute to its effects. Traditionally, it has been used to treat respiratory diseases, fever, and as an anti-inflammatory agent. While research interest in its pharmacological activities is growing, the quality of available evidence is variable, and more studies are needed to confirm its efficacy and safety in humans. Due to the presence of solanine, proper preparation is crucial to avoid toxicity.
Benefits
Research suggests that *Solanum nigrum* possesses several potential health benefits, primarily based on in vitro and animal studies. It exhibits antimicrobial and antioxidant activities, with studies showing its ability to scavenge free radicals and enhance antioxidant enzymes. Some research indicates potential anti-tumor activities, though human clinical trials are limited. Secondary effects suggested by preliminary studies include immunomodulatory, anti-ulcer, and cardio-protective properties. While it may be beneficial for managing oxidative stress and inflammation, the effect sizes and clinical significance are not well-quantified due to the lack of large-scale human studies. Further research is needed to establish the time course of these potential benefits.
How it works
The mechanism of action of *Solanum nigrum* is primarily attributed to its antioxidant activity, where it scavenges free radicals and enhances antioxidant enzymes like superoxide dismutase (SOD) and catalase (CAT). It may interact with the immune and cardiovascular systems, contributing to its purported immunomodulatory and cardio-protective effects. However, the specific molecular targets and detailed biological pathways are not yet well-defined. The absorption and bioavailability of its active compounds have not been extensively studied, limiting a complete understanding of its systemic effects.
Side effects
While generally considered safe when used appropriately, *Solanum nigrum* can be toxic if not properly prepared due to the presence of solanine. Common side effects include gastrointestinal upset if ingested in large quantities. Uncommon side effects may include allergic reactions. Rare side effects involve neurological symptoms resulting from solanine toxicity. Potential drug interactions may occur with medications affecting the liver or cardiovascular system. It is contraindicated in pregnancy, breastfeeding, and individuals with certain gastrointestinal conditions. Caution is advised in children and individuals with compromised health. Proper identification and preparation are crucial to avoid toxicity, and consuming raw or unripe parts should be avoided due to their high solanine content.
Dosage
There is no established minimum effective dose, optimal dosage range, or maximum safe dose for *Solanum nigrum*. Traditional medicine practices often use it without standardized dosing. Due to the potential for toxicity, caution is advised. It is often used as a leaf or fruit extract, but specific form-related recommendations are lacking. Absorption factors and required cofactors are not well-studied. Given the limited research and potential risks, it is essential to consult with a healthcare professional before using *Solanum nigrum*.
