Quick Summary

Sarsaparilla (Smilax ornata) is a plant historically used in traditional medicine, especially in Jamaican folklore, with some research interest in its potential antiviral properties. However, clinical evidence on its medicinal benefits in humans remains limited and pending further validation.

What is it?

Sarsaparilla is a perennial vine native to Central America and the Caribbean. It has been traditionally used for various medicinal purposes. The plant contains roots that are often used in herbal preparations and beverages.

Traditional Uses

Traditionally, sarsaparilla has been used in Jamaican and other Caribbean folk medicine. It has been valued for potential cleansing and tonic effects, and as a treatment for conditions believed to be caused by toxins or impurities in the body.

Active Compounds

Sarsaparilla contains various bioactive compounds, including steroidal saponins, flavonoids, and other phenolic compounds. These constituents are thought to contribute to the plant’s pharmacological activities, although specific active ingredients require further research.

Potential Benefits with Evidence Levels

  • Antiviral activity (Preclinical and ethnobotanical evidence): Research reviews have highlighted sarsaparilla as part of Jamaican medicinal plants with reported antiviral activity, particularly against viruses such as HIV types 1 and 2, hepatitis B and C, influenza A, and SARS-CoV-2. However, this evidence is based on traditional use and preliminary experimental research rather than clinical trials.

Side Effects

There are no documented adverse effects from clinical studies in humans available for sarsaparilla. Safety data specifically for Smilax ornata in humans is not reported in the current literature.

Drug Interactions

No data on drug interactions with sarsaparilla (Smilax ornata) were found in the searched literature.

Who Should Avoid It

Due to the lack of safety information, pregnant or breastfeeding women are advised to avoid using sarsaparilla as its safety during these periods is unknown. Individuals with known allergies to related plants or those taking medications should consult a healthcare professional before use.

Evidence Limitations

  • No published randomized controlled trials or meta-analyses involving sarsaparilla (Smilax ornata) were identified.
  • Available information is based mainly on ethnobotanical reviews and preclinical studies without validated clinical outcome data.
  • Lack of detailed toxicological and pharmacokinetic studies in humans.
  • No studies addressing safety, drug interactions, contraindications, or use in special populations such as pregnant or breastfeeding women.
