TikTok’s avocado-pit hip spray is just rubbing alcohol

Almost all studies on avocado seed and inflammation involve mice and petri dishes.

A TikTok video showing a chopped avocado pit soaked in rubbing alcohol has pulled thousands of likes and comments. Creators spray the liquid on sore joints and say it eases pain. Some versions add cloves or castor oil, but the base recipe is the same: pit, alcohol, spray.

⚡ 10-Second Pulse

Have you tried a food-based pain remedy from social media?

🥑 Yes, including this one 🧊 No, I stick with ice or heat 🤔 I’ve been tempted

Penn State researchers found anti-inflammatory activity in avocado seed extract in a 2019 cell culture study (Dabas et al., Advances in Food Technology and Nutritional Sciences). The extract was a professionally prepared concentrate developed over a decade as a food colorant, not a chopped pit soaked in a jar. A separate 2017 mouse study (Kristanti et al.) used lab-prepared extracts and found reduced paw swelling in mice. Africa Check reviewed the evidence in 2024 and found little to no research on the topical use of avocado seeds on humans.

What people feel from the spray is the isopropyl alcohol evaporating off the skin. That evaporation pulls heat from the surface, constricts blood vessels, and slows nerve signals. A cold pack does the same thing but lasts 15 to 20 minutes. The alcohol is gone in under a minute. Not worth it.

lifetime risk of symptomatic hip OA

cooling from an alcohol spray on skin

For a condition that affects one in four adults over a lifetime (Murphy et al., 2010, Johnston County cohort of 3,068 people), any remedy needs human data behind it.

Rubbing alcohol is not a topical pain treatment. It strips oils from the skin with repeated use, causing dryness, redness, itching, and in some cases contact dermatitis with blistering and cracking. If the skin over your hip is already irritated from this spray, stop using it.

✅ The 15-Minute Test

Grab a bag of frozen peas or a reusable gel pack. Wrap it in a thin towel, place it against the outside of the sore hip, and hold for 15 minutes. The ACR/Arthritis Foundation 2019 guideline conditionally recommends cold therapy for hip OA (Kolasinski et al., 2020). Do it once today. If the ache returns, repeat every two hours (15 minutes on, at least 45 minutes off). If the hip is hot, red, and swollen, or if pain worsens, stop and see a doctor.

●	An avocado joint supplement with trials does exist. Avocado-soybean unsaponifiables (ASU) is a standardized 300 mg oral capsule. A meta-analysis of four RCTs with 664 OA patients (Christensen et al., 2008) found a small but significant pain reduction favoring ASU over placebo. All four trials were manufacturer-funded, and results were weaker for hip OA than knee. If avocado-based joint support interests you, look for ASU capsules, not rubbing alcohol.
●	Exercise carries the strongest clinical recommendation for hip OA. Walking, strengthening, and aquatic exercise all qualify, with no hierarchy among them. Start with a 10-minute walk today.
●	Chest-deep water reduces compression on the hip joint during movement. That makes a pool walk one of the easiest ways to move a sore hip. If you have pool access, try 20 minutes today.

Quick Vote

What do you reach for first when your hip aches?

🧊 Cold (ice pack, frozen peas)

🔥 Heat (heating pad, warm towel)

From the Mailbag

“My hip aches at night and I saw this spray. Is there anything I should try before bed?”

Skip the spray. Heat is a conditionally recommended therapy for hip OA. A warm towel or heating pad on the hip for 15 minutes before getting into bed may ease stiffness enough to help with falling asleep. If hip ache continues despite cold, heat, and daily movement, get the hip evaluated by a doctor.

The Ache Report

P.S. Mouse studies found acute toxicity in an ethanolic avocado seed extract (LD50 of 1,200 mg/kg) but not in a water-based one. The difference comes from what the alcohol pulls out of the seed. Soaking a pit in rubbing alcohol at home runs the same kind of extraction with no dose control. If you have a batch sitting in your cabinet, pour it out.
