Sarsaparilla and asparagus
Sarsaparilla Root and Asparagus in Quietum Plus: Evidence
Sarsaparilla root and asparagus fill tile 7 of the Quietum Plus sales page, two traditional tonic plants with no hearing or tinnitus trials behind them. The page prints no amount for either, and it does not name the asparagus species or the plant part. One small trial tested an asparagus root extract for low libido in women, not for the ears.

01Tile 7
What are sarsaparilla root and asparagus in Quietum Plus?
Two tonic plants, named together on one tile of the sales page, with nothing else said about them.
Sarsaparilla root and asparagus are the seventh of nine ingredient tiles on the Quietum Plus sales page (Quietum Plus sales page). Sarsaparilla is the root of a climbing vine from the Smilax group. Asparagus is the garden plant that most people know as a vegetable.
The page gives each one a name and a photo, and nothing more. It prints no amount, no plant part for the asparagus and no species. The bottle front names no ingredient at all.
Both belong to the tonic herbs in our list of 18. A tonic herb is one sold for general wellbeing rather than for a named condition. That is a use label, not a proof of benefit.
| Name on the sales page | Sarsaparilla Root |
|---|---|
| What it is | Smilax species root, a climbing vine |
| Sales-page tile | Tile 7, no claim of its own |
| Group (ours) | Tonic herbs |
| Amount in a capsule | Not printed |
| Usually sold or studied for | Traditional tonic and flavoring; little human research |
| Research on hearing or tinnitus | No hearing or tinnitus trials found |
| Main caution | We found no safety studies; tell your pharmacist you take it. |

| Main caution | Avoid if you are allergic to asparagus; the species and plant part are not named. |
02Sarsaparilla
What is sarsaparilla root, and are there human studies?
Sarsaparilla root is the dried root of a Smilax vine, used for a long time as a tonic and as a flavoring. We found no human trial of it for hearing, tinnitus, memory or mood in our sources.
That does not mean it is harmful. It means the evidence is missing. For a plant with little research, the honest answer to "does it work?" is "unknown", and the honest answer to "is it safe at the amount in the capsule?" is also "unknown", because the amount is not printed.
The page does not say which Smilax species it uses, and different species are sold under the same name. Tell your pharmacist you take it, as you would with any herb.
03Asparagus
Which part of asparagus is in the capsule, and is it the same as eating asparagus?
The page does not say. It names "Asparagus" with no species, no part and no extract ratio.
Asparagus extract is not the same as eating asparagus. A spear on a plate is a young shoot. A capsule extract can come from the root, the shoot or the seed, and it can be many times stronger than the food.
The only asparagus trial in our sources used a different thing again: a root extract of Asparagus racemosus, also called shatavari, at 300 mg a day for 8 weeks (Satla et al., Shatavari RCT). Seventy healthy women with low libido took it or a placebo. Sexual function scores rose more with the extract, and so did some anxiety, sleep and fatigue scores. It was well tolerated, with no serious side effects.
That is one small trial in one country, in women, about libido. It is not a hearing study. The sales page lists only "Asparagus", so the trial's extract may not match what is in the capsule.
If you react to asparagus as a food, ask your doctor before taking a capsule that lists it without saying which part it uses.
04At a glance
What does the evidence show for tile 7, ingredient by ingredient?
Short answer: one libido trial for one relative of asparagus, nothing for sarsaparilla, nothing for the ears.
The table sets the sales page next to what we found. A blank means we looked and found nothing in our sources, not that nothing exists anywhere.
| Question | Sarsaparilla root | Asparagus |
|---|---|---|
| Amount per capsule | Not printed | Not printed |
| Species or plant part | Not printed | Not printed |
| Hearing or tinnitus trials | None found | None found |
| Human trial of any kind | None in our sources | One, on a shatavari root extract for low libido in women (Satla et al., Shatavari RCT) |
| Main caution | No safety studies found | Food allergy; part and species unknown |
The ingredient grid on the ingredients page shows how this tile compares with the other eight.
05The claim
Where does the "calming effect on the nervous system" claim come from?
The sales page says the formula "May have a calming effect on the nervous system" (Quietum Plus sales page), but it does not say which tile or ingredient that sentence belongs to. We do not assign it to sarsaparilla or asparagus.
The nearest thing to evidence is the shatavari trial above, which also scored anxiety and found lower scores with the extract than with placebo (Satla et al., Shatavari RCT). The women in it had low libido, the dose and extract are unknown for Quietum Plus, and the trial did not test the ears.
The word "may" matters. It marks a possibility, not a result. No study of Quietum Plus supports it.

Can asparagus extract act as a diuretic, and should I check my medicines?
Asparagus is traditionally described as a diuretic, a substance that makes the body pass more urine. We found no trial in our sources that tests that for the extract in Quietum Plus, so we cannot say whether the capsule does it.
If you take a water pill, a blood pressure medicine or any daily prescription, show the bottle to your pharmacist. The sales page itself asks buyers to show the bottle to a doctor first (Quietum Plus sales page, claims). Quietum Plus also lists dong quai, ginger and ashwagandha, which matter more for interactions. See the dong quai page and side effects.
Do not stop or change a prescribed medicine because you started a capsule. Only your doctor should do that.
07Ringing in the ears
Do sarsaparilla or asparagus help ringing in the ears?
No trial shows that sarsaparilla or asparagus helps tinnitus. The NIDCD says that no supplement advertised for tinnitus has been shown to work (NIDCD, Tinnitus). The 2026 US guideline advises clinicians not to recommend supplements for persistent, bothersome tinnitus (AAO-HNSF Tinnitus Update 2026).
Ringing that is new, in one ear only, or that comes with hearing loss needs a hearing exam first. Sudden hearing loss in one ear needs a doctor the same day.
When ringing is a doctor question, not a supplement question
Sudden hearing loss in one ear (same day), ringing that beats with your pulse, ringing after a head injury, or ringing with dizziness, weakness or a drooping face. Call 911 for sudden weakness or a drooping face. Sources: NIDCD on sudden deafness (NIDCD, Sudden Deafness), the NHS (NHS, Tinnitus), Mayo Clinic (Mayo Clinic, Tinnitus) and the tinnitus guideline (AAO-HNSF Tinnitus Guideline 2014).

09FAQ
Sarsaparilla and asparagus questions
What is sarsaparilla root?
Sarsaparilla root is the dried root of a Smilax vine, used for a long time as a tonic and flavoring. We found no human trial of it for hearing, tinnitus or mood, and Quietum Plus prints no amount or species (Quietum Plus sales page).
Which part of asparagus is in the capsule?
The sales page does not say. It lists "Asparagus" with no species, no plant part and no amount (Quietum Plus sales page). The root, shoot and seed are different materials, so ask the order desk or read your bottle before you rely on any study.
Are there human studies of sarsaparilla?
None turned up in our sources for hearing, tinnitus, memory or mood. Sarsaparilla is a tonic plant with little modern research, so its benefits and its safety at capsule amounts are both unknown.
Can asparagus extract act as a diuretic?
Asparagus is traditionally called a diuretic, but we found no trial that tests the extract in Quietum Plus. If you take a water pill or any daily medicine, show the bottle to your pharmacist before the first capsule.
Where does the 'calming effect on the nervous system' claim come from?
The sales page prints "May have a calming effect on the nervous system" without naming a tile or a source (Quietum Plus sales page). A trial of a shatavari root extract in women with low libido scored anxiety too (Satla et al., Shatavari RCT), but it did not test Quietum Plus.
Is asparagus extract the same as eating asparagus?
No. Eating asparagus gives you a young shoot in food amounts. An extract can come from the root or seed and be far more concentrated. The trial in our sources used a shatavari root extract at 300 mg a day (Satla et al., Shatavari RCT).
