Nanotech Health doesn’t sell registered flu medicines like Corenza C or ACC 200 — for those, see our Corenza C vs ACC 200 comparison guide. What we make is a range of colloidal silver products for everyday nasal, throat and general use through cold and flu season. From R60, delivered nationwide. Free delivery over R500.
The range
- Silver Throat Spray 25ml — R80. A fine mist aimed at the back of the throat. Alcohol-free and sugar-free — popular with teachers, singers and anyone whose throat feels the strain of talking all day.
- Silver Nasal Spray 20ml — R60. A gentle daily mist for nasal comfort through dry Highveld winters and blocked-up days.
- Colloidal Silver 200ml — R90. Our everyday liquid colloidal silver, taken orally, in a generous bottle that lasts through the season.

Questions
Is this the same as flu medicine like Corenza C or ACC 200?
No. Those are registered pharmacy medicines and we don’t sell them. Our colloidal silver range is a separate category of product — see our Corenza C vs ACC 200 guide if you’re comparing the two options.
Can I use the throat spray and nasal spray together?
Yes — they’re designed for different areas and are commonly used alongside each other.
How long does delivery take?
Orders to major South African centres typically arrive within 1–2 business days. Delivery is free on orders over R500.
What if it’s not right for me?
You have 30 days from delivery to return it. We pay for the return courier and refund your original delivery charge in full.
