No Known Interaction
The bottom line No known interaction

We found no known interaction between Black Nightshade and Botulinum Toxin Type A in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Black Nightshade and Botulinum Toxin Type A

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Botulinum Toxin Type A and Black Nightshade in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Black Nightshade at all — not against Botulinum Toxin Type A, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

About Black Nightshade

What is Black Nightshade?

Black Nightshade
  • Digestive complaints
  • Skin conditions
  • Inflammation
  • Fever
  • Liver support (traditional)

Black nightshade is a wild plant whose cooked ripe berries and leaves are eaten as food in some cultures, but unripe berries and green parts can be poisonous. Human evidence for any health benefit is very limited, and the risk of toxicity is real. Do not use it as a supplement without medical guidance, and avoid it during pregnancy and breastfeeding.

Solanum nigrum · Solanaceae · Leaves, berries (ripe), and whole plant · Cooked leafy greens, fruit, traditional decoctions, dried herb, extracts

An interaction check asks whether these two react with each other — it does not ask whether Black Nightshade is a good idea for someone in your situation. Here is what our Black Nightshade record says about it on its own.

Black Nightshade: dosing

There is no established or standardized safe dose of black nightshade as a supplement. When it comes to wild plants, never guess at an amount or forage your own to use as medicine.

About OnabotulinumtoxinA Injection

What Is OnabotulinumtoxinA Injection Used For?

Brand name: Botox

Botox is approved to treat a wide range of conditions in adults and some children. These include overactive bladder (OAB) with urge incontinence, urinary incontinence caused by nerve-related bladder overactivity (in adults and in children aged 5 and older), prevention of headaches in adults with chronic migraine (15 or more headache days per month), muscle stiffness (spasticity) in patients aged 2 and older, cervical dystonia (abnormal head position and neck pain), severe underarm sweating (primary axillary hyperhidrosis) when topical treatments haven't worked, eyelid spasms (blepharospasm) in patients aged 12 and older, and crossed eyes (strabismus) in patients aged 12 and older.

BOTOX Cosmetic is a separate product containing the same active ingredient but with its own approved cosmetic uses. Both products are given by injection and are not interchangeable with other botulinum toxin products. Botox has not been shown to work for episodic migraine (14 or fewer headache days per month), and its safety for excessive sweating in body areas other than the underarms has not been established.

Most-Reported Side Effects for Botulinum Toxin Type A

From FAERS, the FDA’s public side-effect reporting system (12,344 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
