What Common houseleek is, and what it does.
- Does it work
- Suits people drawn to traditional European garden plants who are comfortable that the human research sits at six published records. Anyone wanting settled human data has fuller options.
- How much to take
- There's no official dose. The few studies on a specific extract used 200-400 mg daily. Best bet is to follow the product label and don't expect miracles.
- Time to feel it
- Nobody has measured a timeline for this in people. Traditional use was on skin, where the cooling of the fresh juice is immediate.
- The first dose
- Nothing. Any effect would be slow and cumulative over weeks or months.
- With regular use
- The theoretical benefit would be a reduction in recurring UTIs or improved skin resilience. But this is based on very early science. We need more data.
- How well tolerated
- Seems generally well tolerated based on a long history of traditional use. However, formal safety studies are lacking. Stop if you get any stomach upset.
- How it feels
- Taken by mouth it is unremarkable, slightly astringent. On skin the fresh juice is cool and a little slippery, which is the part people actually describe.
- The overlooked benefit
- The leaf is mostly water held in mucilage, which is why the split juice feels cool and slippery. That texture is why it turns up in gels far more often than capsules.
500 to 1,000mg a day is where Common houseleek works.

The proof, claim by claim.
These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.
Common houseleek is documented in the library; the clinical read is in the queue. Nothing about the strength of the research prints until the read is done.

Questions people ask about Common houseleek.
- Is this the same as Aloe vera?
- No. They were used for similar skin issues in folk medicine, but they are completely different plants from different parts of the world.
- Can I just eat the 'Hens-and-chickens' from my garden?
- Bad idea. You don't know the dose, concentration, or if it's been exposed to contaminants. Stick to a properly manufactured supplement.
- Does it actually work for UTIs?
- Maybe, but the evidence is weak. A specific extract has shown some promise, but it's far from proven. D-Mannose and cranberry have much more research backing them.
- Can it replace antibiotics for a UTI?
- Absolutely not. If you have an active UTI, you need to see a doctor. This is only being explored for prevention, not treatment.
- Are there any side effects?
- Unlikely at standard doses, but the data is very limited. Mild stomach upset is the most likely issue. Stop taking it if it bothers you.
- What does 'Sempervivum tectorum' mean?
- 'Sempervivum' means 'live forever' in Latin, because it's a very resilient plant. 'Tectorum' means 'of roofs', because it was famously grown on them.

Nothing on file for Common houseleek, either from a combination trial or from settled biochemistry. When either lands, it appears here with its source.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
