The Science of Fast Relief

Not just zinc. Not just Vitamin C.
A plant that fights back.

Pelargonium sidoides works through four distinct biological pathways to help relieve the symptoms of colds and upper respiratory tract infections, and to help reduce how long they last.

Origin & History

Rooted in African tradition. Validated by modern science.

Pelargonium sidoides is a medicinal plant native to the highlands of South Africa, used for generations in traditional Zulu and Basotho medicine for respiratory complaints, fever, and fatigue.

Modern clinical research has confirmed what traditional healers knew — its root extract acts through four simultaneous biological mechanisms, making it one of the most well-studied herbal remedies for cold and upper respiratory tract infections.

  • Used in traditional South African medicine for over 200 years
  • Over 20 clinical studies supporting safety and efficacy

Mode of Action

Four ways it works. All at once.

Most cold remedies work on one thing. Cold Formula was built around four.

Support from the first sign of symptoms
At First Onset
Support From the First Sign
Pelargonium sidoides is meant to be taken the moment symptoms start, which is when it has been most studied. Begin at the scratchy-throat stage rather than waiting to see how bad it gets.
Upper respiratory support
Respiratory Support
Upper Respiratory Support
Helps relieve the symptoms that settle in the upper respiratory tract during a cold, including sore throat, cough and runny nose.
Immune Modulation
Balanced Immune Support
Immune Modulation
Works with your immune system rather than simply stimulating it, which is why it is described as modulating rather than boosting.
Mucus-Clearing Respiratory Support
Mucus Clearing
Mucus-Clearing Respiratory Support
Helps loosen and thin mucus in the airways, making it easier to clear congestion and breathe more comfortably while your body works through recovery.

FAQ

Common questions

Pelargonium sidoides is a medicinal plant native to South Africa, traditionally used for respiratory complaints. Its root extract has been studied in over 20 clinical trials and is licensed by Health Canada under NPN 80114231 to help relieve the symptoms of, and reduce recovery time from, upper respiratory tract infections including the common cold, bronchitis, laryngitis and pharyngitis.
Most cold remedies work through a single pathway — Vitamin C supports the immune system, Echinacea has mild immune-stimulating effects. Pelargonium sidoides was chosen because it works on four fronts at once: symptom relief, upper respiratory support, immune modulation, and clearing mucus.
Begin at the very first sign of symptoms — a scratchy throat, runny nose, or unusual fatigue. Early intervention is when Pelargonium sidoides is most effective. Take 1 capsule 3 times daily (adolescents and adults) or 1 capsule 2 times daily (children 6–11), 30 minutes before or after meals. Consult a health care practitioner for use beyond 7 days.
Cold Formula is generally well-tolerated. However, if you are taking prescription medications, are pregnant or breastfeeding, or have a chronic health condition, please consult your healthcare practitioner before use. Not recommended for children under 6 without professional guidance.
NPN 80114231 is a Natural Product Number issued by Health Canada. It confirms that Cold Formula has been reviewed and approved for the specific health claims listed on the label. Products with an NPN have demonstrated evidence of safety, efficacy, and quality under Canadian regulatory standards.

Works Well

My husband tried this when he was suffering from a cold. He believes it helped him get over his cold quicker than normal. He only took one pill and he quickly started to feel better. The capsules are easy to swallow. Assuming you take the recommended dosage and you take it for five days, this would be good for up to four colds.Although this seems expensive, I actually think it is worth it. For future colds my husband is insisting that we only use this cold formula and to always have some on hand. His reasoning is that it stops the cough, eases the breathing and gets rid of the feverish feeling and weakness of a cold. Each time, within half an hour he noticed a difference.

It really works

I was skeptical. Then I finally had an opportunity to give this a whirl and let me tell you…it actually works.When I get sick my colds generally turn pretty bad in the respiratory department. Horrible coughing that is hard to control. The kind where you feel like you have crap stuck in your throat but no matter how hard you cough it won’t dislodge. It’s horrible.I started taking these as soon as I knew I was developing a cold and WOW. My symptoms were 5x better than they normally would be. I also noticed that I recovered more quickly.Definitely worth a try!

Really good

This hill is actually surprisingly great. Not only does it do what it says it does but , it’s super easy to swallow and you can feel results.The pill bottle is the average size but because I seen the results quickly, I would definitely say that you’re getting your moneys worth when you make this purchase.

Great Product

Had a persistent cough that would not go away, Everyone I knew seemed to have the same thing. Someone recommended Cold Formula and I went straight out and bought a box. That was the first night that I was able to get a full nights sleep, that I wasn't awakened from coughing. it did take some time but eventually I was able to get rid of the cough.
