Clematis Recta Drug Interactions, Uses, Safety & More
What is this page for?
First and foremost: how Clematis Recta interacts with medications. The heart of this page is the interaction list — every drug Clematis Recta is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Clematis Recta is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Overview
Clematis recta is a climbing or upright flowering plant in the buttercup family (Ranunculaceae). It grows in parts of Europe and Asia and produces clusters of small white flowers. It is sometimes called upright virgin's bower.
Like many plants in its family, the fresh plant contains irritating compounds and is considered toxic if eaten or applied raw. Because of this, it is almost never used as a food or a regular herbal tea. Today it is most often found as a homeopathic remedy, where the plant material is diluted many times.
In traditional and homeopathic practice, people have used it for skin problems, swollen glands, and certain types of nerve or urinary discomfort.
Uses & effectiveness
People have traditionally used Clematis recta for skin eruptions, swollen lymph nodes, urinary complaints, and nerve pain. In homeopathy it is also a common remedy for groin and testicular discomfort in men.
The scientific evidence behind these uses is very weak. There are no high-quality human studies showing that Clematis recta treats any of these conditions. Most of what is known comes from traditional use and homeopathic texts rather than from modern clinical trials.
If you are considering it for a specific health problem, treat it as unproven and talk with a pharmacist or doctor first, especially since untreated conditions like infections or persistent swelling may need real medical care.
How it works
Plants in the Ranunculaceae family, including Clematis recta, contain a compound called protoanemonin, which is released when the fresh plant is crushed. This compound is irritating to skin and mucous membranes and is the main reason the raw plant is considered toxic.
There is no well-established mechanism explaining how Clematis recta would treat any disease. In homeopathic products, the plant is diluted so much that little or none of the original material remains, so any proposed effect is based on homeopathic theory rather than a measurable pharmacological action.
Overall, claims about how it works are based mostly on tradition and limited laboratory observations, not on solid human research.
Safety & precautions
The raw or concentrated plant is not safe to eat or apply directly. Protoanemonin can cause burning, blistering, and irritation of the skin, mouth, and digestive tract.
Highly diluted homeopathic forms are generally considered low-risk because they contain very little plant material, but this does not mean they are proven to help. People with sensitive skin, allergies to plants in the buttercup family, or chronic health conditions should be especially careful.
Pregnancy and breastfeeding: Because there is no reliable safety information, Clematis recta should be avoided during pregnancy and while breastfeeding. Children should not use it unless a qualified healthcare provider recommends it. When in doubt, check with your pharmacist or doctor before using any product containing this plant.
Side effects
With the raw or strong plant, the main risks are skin irritation, blistering, mouth and throat burning, nausea, and stomach upset. Contact with the fresh plant can cause redness and rash.
Highly diluted homeopathic products are less likely to cause these problems, but allergic reactions are still possible. Stop using it and seek care if you notice rash, swelling, trouble breathing, or any reaction that worries you.

Dosing
There is no established standard dose for Clematis recta. The raw plant is not recommended at all because it is toxic and irritating.
When sold as a homeopathic remedy, it comes in standardized dilutions and potencies set by the manufacturer. If you choose to use it, follow the directions on the product label exactly, and do not assume that a higher amount is safer or more effective.
Because dosing is not well defined and the plant carries real safety concerns, it is best to check with a pharmacist or doctor before starting.
