And on a less efficacious, more aesthetic note, many of these natural exfoliating formulas often deliver the same sleek aesthetics in their packaging and experience as prestige skin-care products. (Conçetta Ciarlo, Why I'm Opting for Exfoliating Deodorants This Spring, Vogue, March 2026)
At the end of the day, to suggest that plant medicine is not efficacious feels pretty silly to me. (Rachel King, The founder of wellness startup Mab & Stoke on the growth of 'pay what you can' options during the pandemic, Fortune, September 2020)
The muses may hold a pen in one hand and a smoke, or steaming mug, in the other - herbal remedies continue to be efficacious for writer’s block. (Alison Habens, A Brief History of the Muses, JSTOR Daily, October 2024)

Origin:
'sure to have the desired effect' (often of medicines), 1520s, from Latin
efficaci-, stem of
efficax 'powerful, effectual, efficient,' from stem of
efficere 'work out, accomplish' + -
ous. (Online Etymology Dictionary)
Efficacious came to English from the Middle French word efficace (or that word's Latin source, efficāc- or efficāx), meaning 'effective'. (These words ultimately trace back to the Latin verb efficere, 'to make, bring about, produce, carry out'.) English speakers added -ious to effectively create the word we know today. Efficacious is one of many, er, eff words that mean 'producing or capable of producing a result'. Among its synonyms are the familiar adjectives effective and efficient. Efficacious is more formal than either of these; it's often encountered in medical writing where it describes treatments, therapies, and drugs that produce their desired and intended effects in patients.

Hi there! Hope the weekend's been treating you well. :3 Welcome to our weekly Lonely Prompts day. If this is your first time at
How to look for prompts:
We have plenty of prompts that might just nibble away at your brain today. You can browse through the comm's calendar archive (here on LJ or here on DW) for themed and Free For All posts, or perhaps check out Sunday posts for Lonely Prompt requests. (Or, you can be like me, and try to save interesting prompts as you see 'em... and then end up with multiple text doc files full of [themes + links + prompts] that you can easily look through and search for keywords.) Multiple fills for one prompt are welcome, by the way! Oh, and you are very likely to find some awesome fills to read as well, and wouldn't it be nice to leave a comment on those lovely little writing distractions? ~_^
Whichever you decide to do, prompt or fill (or both), please remember:
1. You can only request five prompts to be filled.
2. You can request no more than three prompts from a particular fandom.
3. You can, however, fill as many prompts in as many fandoms as you'd like!
4. In the subject line, be sure to say whether it is a request or a fill!
5. You must link back to wherever the prompt is in the community archive (whether filling or requesting), and, if you're filling the prompt, please post the fill as a reply to the original prompt.
6. If you are filling an "any/any" prompt, please let us know what fandom you've written it for (or if it's original!).
8. If there are possible triggers in your story, please warn for them in the subject line!
7. If you've filled any lonely prompts in the past week, this is the place to share them!
9. Finally, please remember to add your prompt fills to our AO3 collection: Bite Sized Bits of Fic from 2026 collection. See further notes on this option here.
