Pulsatilla 3C HPUS
Also known as: Pulsatilla, Pasque flower, Wind flower, Pulsatilla 3C HPUS, Pulsatilla chinensis
Overview
Pulsatilla encompasses both a homeopathic remedy (Pulsatilla 3C HPUS) and extracts from the Pulsatilla chinensis plant used in traditional Chinese medicine (TCM). The homeopathic preparation involves extreme dilutions, while TCM utilizes extracts containing bioactive compounds like Pulsatilla saponins. Homeopathic Pulsatilla 3C is traditionally used for respiratory and otorhinolaryngologic symptoms. Pulsatilla chinensis extracts are investigated for anti-cancer and anti-inflammatory properties. Homeopathic Pulsatilla's efficacy lacks strong clinical evidence, with studies showing inconsistent results. Research on Pulsatilla chinensis extracts is more robust preclinically, demonstrating anti-cancer mechanisms, but requires further clinical validation. The quality of evidence for homeopathic Pulsatilla 3C is generally low to moderate, while extracts have promising mechanistic data but lack large clinical trials. It's important to distinguish between the highly diluted homeopathic preparation and the pharmacological extracts.
Benefits
Systematic reviews of homeopathy, including Pulsatilla, show no consistent, statistically significant benefit for upper respiratory tract infections or otorhinolaryngologic infections compared to placebo or standard treatment. Some small trials report symptom improvement or reduced use of symptomatic medication in children with URTIs, but results are not consistently replicated and effect sizes are small. Pediatric populations have been studied most frequently, but no conclusive evidence supports Pulsatilla 3C’s efficacy in children with respiratory infections. Pulsatilla saponin D (PSD) shows in vitro anti-cancer effects by inducing apoptosis in lung adenocarcinoma and hepatocellular carcinoma cells, modulating mitochondrial apoptotic pathways and PI3K/Akt/mTOR signaling. Clinical applications in cancer patients are preliminary and mostly observational, with some reports of symptom improvement during adjunctive therapy.
How it works
The mechanism of action differs significantly between homeopathic Pulsatilla 3C and Pulsatilla extracts. Homeopathic Pulsatilla 3C relies on the principle of 'like cures like' through extreme dilution, lacking a scientifically established biochemical mechanism. In contrast, Pulsatilla extracts, particularly PSD, induce apoptosis via downregulation of BCL-2 and caspase-3, and modulate PI3K/Akt/mTOR pathways critical in cell survival and proliferation. These molecular targets are well characterized in cancer biology. For homeopathic 3C, pharmacokinetics are not applicable due to extreme dilution. For extracts, bioavailability data are limited, but saponins generally have moderate absorption.
Side effects
Homeopathic Pulsatilla 3C is generally considered safe due to its high dilution, posing minimal risk of toxicity. No significant adverse events have been reported in reviewed RCTs, and drug interactions or contraindications are not established. Pediatric use is common in homeopathy, but its efficacy remains unproven. In contrast, Pulsatilla-based TCM compounds have reported some adverse effects in cancer patients, including neutropenia, vomiting, and diarrhea. However, these effects are associated with complex formulations rather than isolated Pulsatilla. Overall, while homeopathic Pulsatilla 3C appears safe, caution is advised with Pulsatilla extracts, particularly in vulnerable populations or when combined with other medications.
Dosage
For homeopathic Pulsatilla 3C, typical dosing follows homeopathic practice, involving oral administration of a few pellets several times daily. However, there is no standardized dosing supported by clinical trials. Experimental doses of Pulsatilla extracts in vitro are in micromolar ranges, but clinical dosing is not standardized. Homeopathic treatments are usually administered over days to weeks, depending on symptoms. Homeopathic pellets or liquid dilutions are used for 3C, while extracts are used in TCM formulations. Due to the lack of robust clinical evidence, specific dosage recommendations for either homeopathic Pulsatilla 3C or Pulsatilla extracts cannot be definitively established.
FAQs
Is Pulsatilla 3C effective for respiratory infections?
Current high-quality evidence does not support efficacy beyond placebo for upper respiratory infections. Systematic reviews of homeopathy show no consistent benefit.
Is it safe for children?
Yes, homeopathic Pulsatilla 3C is generally safe due to high dilution, but lacks proven benefit for pediatric respiratory infections.
How quickly does it work?
There is no reliable data on the time course of action. Any reported symptom improvement is anecdotal and not supported by clinical trials.
Is it the same as Pulsatilla extract?
No, homeopathic 3C is a highly diluted preparation, while extracts contain active compounds studied pharmacologically for anti-cancer and anti-inflammatory effects.

The review found no consistent benefit over placebo or standard care, with limitations including heterogeneity and small sample sizes. Outcomes included symptom severity and duration in children, but the quality of evidence was moderate.
- https://www.hri-research.org/wp-content/uploads/2014/07/Homeopathy-Overview-Report.pdf – This comprehensive evidence synthesis assessed the effectiveness of homeopathy for various clinical conditions, including those treated with Pulsatilla. The report found insufficient evidence to support homeopathy's effectiveness, citing methodological limitations and inconsistent results in included RCTs. No significant effect sizes were demonstrated, indicating a lack of clinical benefit.
- https://www.frontiersin.org/journals/oncology/articles/10.3389/fonc.2022.888075/full – This systematic review summarized experimental and clinical research on the anti-cancer activity of Pulsatilla saponins. In vitro studies showed apoptosis induction via mitochondrial and PI3K/Akt/mTOR pathways. Clinical data were limited to small observational studies with some symptom improvement in cancer patients, highlighting the need for high-quality RCTs to confirm therapeutic benefits.

It details the methodology and specific studies reviewed in their assessment of homeopathy's effectiveness. The conclusion remains that there is a lack of high-quality evidence to support the use of homeopathy for any health condition.
