A single mother has advised others to ingest semen if they want to avoid a winter cold.
Tracy Kiss, 29, from Buckinghamshire, says that she has enlisted the help of her best friend to supply her with his sperm in order to boost her immunity.
Despite being vegan Tracy says she is prepared to use the byproduct in the pursuit of better health.
The single mother adds the questionable ingredient to her morning smoothie every day claiming that it has plenty of health benefits.
The mother-of-two said that when she first approached her friend her was concerned that she would use his fluids to impregnate herself but soon came round to the idea.
Tracy says that she has chosen a none smoking friend who cleared an STI test to be on the safe side.
The personal trainer says that she is quite prepared to drink the semen neat but adds extra ingredients if her mate has enjoyed a couple of pints.
She added: 'If he's been drinking alcohol or eaten something particularly pungent like asparagus, I ask him to give me a heads up so I know not to drink it neat.'
This is not the first time that Tracy has introduced the unusual ingredient into her beauty regime.
Tracy admitted that she uses her friends semen for a rather extreme facial on her YouTube channel last year.
The mother described how said friend delivers his semen to her in plastic pots from the Chinese takeaway, which she then rubs into her skin and leaves to sink in for up to 20 minutes.
She said: 'I think people are concerned with the thought of putting semen on their face but actually it's a very natural and healthy thing to do.'

The single mother suffers from the skin condition rosacea, which causes redness and flushing, and says her daily facial has done wonders for improving her complexion.
'I know there are no added chemicals. It's as natural and active and live as you could possibly get,' she explained.
After describing her skin condition to viewers, she held up a small pot containing the sperm donated by her friend.
She stressed that she's 'not involved' in the donation, and that it's a result of something her friend would be doing on a daily basis anyway.
But she reminds viewers who are in relationships that they can call on their partners for help.
Tracy then dips her fingers into the pot and wipes the substance onto her cheeks.
She describes the sensation it gives as 'cooling and soothing' and likens it to eating minty chewing gum.
'I would put it in comparison to when you have chewing gum in your mouth and you breathe in, it's a cold, cooling, refreshing feeling,' she said. 'It just sucks into the skin. It's absolutely beautiful.'
Tracy explains that she doesn't mind the smell, and says that if the donor eats a healthy, balanced diet the sperm will have a fresher odour.
But she advises anyone who wants to try it to burn some incense or keep a diffuser nearby if they are squeamish.
Tracy leaves the substance on her face for between five and 20 minutes before wiping it off and washing her face with warm water.
'It feels so glossy to wipe it off. It feels like having a kind of oil on the face,' she explained. 'It just glides beautifully.

'The condition of the skin feels so much better already.'
The former glamour model's video has had several hundred views since being posted online yesterday, but Tracy has already written about the procedure on her website.
She said the idea came about during a conversation about natural remedies with her beauty therapist.
