The BBC has been forced to pull down a recent episode from its streaming service after a guest showcased so-called "ear seeds".
Giselle Boxer, 31, received a £50,000 investment from Stephen Bartlett for a 12.5 per cent return in her business.
However, Boxer's business was allegedly subsequently reported to the Advertising Standards Agency after doctors and "vulnerable sick people" wrote letters of complaint.
They claimed the product was giving patients "false hope".

Boxer categorically rejected the allegations about her product, describing them as "unproven" claims.
The BBC responded by pulling the episode which aired on January 18.
A BBC spokesperson told The Sun: "We're taking the concerns raised seriously, so we are reviewing the episode and therefore it's currently not available on iPlayer."
The broadcaster was forced to back-peddle on the product, having previously defended Boxer's wellness business.

Ear seeds are tiny needle-less beads, based on acupuncture principles.
They are applied to the ear in an attempt to stimulate nerve endings.
Boxer claimed her recovery inspired her to set up Acu Seeds with the aim of helping others recover from similar conditions.
