Pippali Extract
Also known as: Pippali, Long Pepper, Piper longum
Overview
Pippali Extract is derived from the fruit of Piper longum, a plant widely used in traditional Indian (Ayurvedic) medicine. It contains multiple bioactive phytochemicals, including piperine, which are responsible for its therapeutic properties. Traditionally, it has been utilized for respiratory disorders, digestive issues, and as an immunomodulator. The extract is characterized by its pungent taste and the presence of alkaloids, amides, and essential oils. Research on Pippali is moderately mature, with increasing pharmacological studies and some systematic reviews, but large-scale clinical trials are still limited. Evidence quality varies, with many studies being preclinical or small clinical trials; however, recent systematic reviews and meta-analyses have begun to consolidate findings.
Benefits
Pippali shows promising benefits across several health areas. For respiratory health, a randomized clinical study demonstrated that a herbal formulation containing Pippali significantly improved lung function parameters (FVC, FEV1, MVV, FEF) and reduced respiratory symptoms like cough and dyspnea in traffic police exposed to air pollution over 28 days (p < 0.001). Network pharmacology and molecular docking studies have identified phytochemicals in Pippali that regulate human protein targets involved in neurological disorders and immune response, suggesting immunomodulatory and neuroprotective effects. A systematic review highlighted its traditional use and pharmacological evidence for anti-inflammatory, antioxidant, and metabolic regulatory effects, though clinical evidence in these areas is still limited. Furthermore, a recent meta-analysis on ovariectomized mice suggests Pippali may improve bone density and reduce bone loss, indicating potential benefits in postmenopausal osteoporosis.
How it works
Pippali's bioactive compounds, particularly piperine, modulate multiple biological pathways, including anti-inflammatory, antioxidant, and neuroprotective pathways. It interacts with various protein targets involved in neurotransmission, immune regulation, and metabolic processes. Piperine is also known to enhance the bioavailability of other compounds by inhibiting drug-metabolizing enzymes and modulating membrane dynamics, which can improve the absorption and efficacy of co-administered substances. In the context of respiratory health, the extract is believed to influence lung function by reducing eosinophilic inflammation and oxidative stress, thereby alleviating symptoms and improving pulmonary parameters.
Side effects
Pippali extract is generally considered safe when used in traditional doses. A clinical study reported no serious adverse effects over a 28-day period. Common side effects are not extensively documented but may include gastrointestinal discomfort in some individuals. There are no significant drug interactions or contraindications that have been robustly reported in clinical trials. However, due to piperine's known ability to inhibit drug-metabolizing enzymes, caution is advised when combining Pippali with other medications, as it could potentially alter their metabolism. Safety data for pregnant or breastfeeding women are lacking, and therefore, caution is advised for these populations.
Dosage
The optimal dosing for Pippali extract is not yet well-established due to limited large-scale randomized controlled trial data. However, a clinical trial investigating respiratory benefits used a dose of 250 mg twice daily of a standardized Pippali-containing formulation, administered for 28 days. For other indications, specific dosing recommendations are less clear. It is important to note that the bioavailability of Pippali's active compounds, particularly piperine, can be enhanced when co-administered with other substances or when formulated for improved absorption. Upper limits and safety thresholds for long-term use are not definitively established, and consultation with a healthcare professional is recommended for personalized dosing advice.
FAQs
Is Pippali effective for respiratory disorders?
Yes, evidence from a randomized clinical trial supports that a Pippali-containing formulation can improve lung function and reduce symptoms related to pollution-induced respiratory issues.
Is it safe for long-term use?
Long-term safety data for Pippali are limited. Short-term use, as studied in clinical trials, appears to be safe at recommended doses.
Can it be combined with other medications?
While no major interactions have been robustly reported, caution is advised due to piperine's potential to inhibit drug-metabolizing enzymes, which could alter the effects of other medications.
What are the main active compounds in Pippali?
The primary active compounds in Pippali are alkaloids, especially piperine, along with amides and essential oils, which contribute to its therapeutic properties.

- https://accscience.com/journal/AJWEP/12/2/10.3233/AJW-2015-12_2_12 – This open randomized clinical trial (Kapgate et al., 2015) investigated the effects of a herbal formulation containing Pippali on traffic police exposed to air pollution. The study found significant improvements in lung function parameters (FVC, FEV1, MVV, FEF) and a reduction in respiratory symptoms (cough, dyspnea) over 28 days, suggesting benefits for respiratory health. Despite its open-label design and small sample size, the statistical significance of the findings is notable.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC5761900/ – This in silico study (Mishra et al., 2017) utilized network pharmacology and molecular docking to identify bioactive phytochemicals in Pippali. It successfully identified 20 drug-like compounds that target human proteins relevant to neurological and immune diseases, providing a mechanistic basis for its traditional uses and suggesting potential immunomodulatory and neuroprotective effects. The study is hypothesis-generating and requires experimental validation.
- https://pubmed.ncbi.nlm.nih.gov/31568819/ – This systematic review (Yadav et al., 2020) summarized the ethnopharmacological and pharmacological evidence for Pippali's traditional uses. It highlighted its anti-inflammatory, antioxidant, and neuroprotective effects, supporting its potential in metabolic and inflammatory conditions. While comprehensive in its review of preclinical data, it noted the limited clinical evidence, indicating a need for more human trials.
- https://onlinelibrary.wiley.com/doi/10.1002/mnfr.202400698?af=R – This systematic review and meta-analysis (Jin et al., 2024) focused on animal studies, specifically five studies involving ovariectomized mice as a model for osteoporosis. The findings suggest that Pippali may improve bone density and reduce bone loss, indicating a potential role in managing postmenopausal osteoporosis. While providing strong preclinical evidence, the direct applicability to human bone health requires further clinical investigation.
