Open questions — adulterated-herbal-creams (round 1)

• How common is steroid adulteration across “herbal”/“natural” eczema creams sold online today (not just clinic samples of creams parents rated as miraculous)? No population-level market survey found; UK studies date from 1999–2003.
• What is the safest way to taper a toddler off a suspected clobetasol-adulterated cream after weeks of daily use, and should adrenal function be tested before stopping? Guidance specific to adulterated products not found.
• Are MHRA-named products (Yiganerjing, Zudaifu) still circulating via marketplaces after 2018, and has the MHRA or UK Trading Standards issued later alerts or prosecutions? Not established this round.
