Sinulex® Forte’s range of products support the immune system and helps the body to cope better with viral and bacterial conditions.

Sinulex® Forte Capsules, Vit C Fizzy, and Syrup help to relieve the symptoms of sinus inflammation, congestion, colds, and flu.


Pathogens are continually adapting and they often develop resistance to the effects of antibiotics and inoculations. In the light of inappropriate antibiotic use and increasing drug resistance, the need for an alternative, effective remedy for sinusitis, colds and flu is crucial. Our ever-growing understanding of molecular techniques, plant immune systems and their mechanisms for pathogen inhibition drives us to develop advanced plant-based medicines from the fundamental understanding that plants have developed a complex defence system against pathogens to survive.

The ingredients in Sinulex® Forte are backed by clinical data that show their efficacy in the fight against viral and bacterial infections. The result: a reduction in the severity of symptoms of nasal congestion, sinus pressure, inflammation of the sinus cavities, postnasal drip, relief from head colds, and general cold and flu symptoms.

Sinulex® Forte is lactose-, tartrazine- and sugar-free, and does not contain pseudoephedrine or any stimulants such as caffeine.


Sinulex® Forte is a natural product range of pharmaceutical-grade quality. Once we have developed a formula, the next step is to choose our raw materials based on quality and sustainability. During the development stage, product standardization, quality control and assurance are essential components in the manufacturing process.

An integral part of manufacturing is to conduct chemical, pharmacological, and toxicological evaluations at multiple stages of manufacture – from raw material to finished product. The bioactive properties of the plant material undergoing processing are also certified, and we provide a certificate of analysis for active and inactive ingredients.

What is sinusitis?

The four paranasal sinuses – frontal, two maxillary, and sphenoidal – drain into the nasal cavities. Any infection or cold in the nose can therefore easily spread into the sinuses. From there, it can involve the back of the throat, and then move down to the bronchi and lungs.

Sinusitis is inflammation of the lining of the sinuses, caused by a viral or bacterial infection, allergic reactions, or an obstruction. Sinusitis is usually divided into two main types:

  1. infections – viral, bacterial or fungal, and
  2. allergies.

In both types, one sees an inflammatory process that is sometimes difficult to differentiate. It is, however, true that a case of severe allergic sinusitis may develop into a sinus infection. The allergic condition may result in swelling of the mucous membrane and a filling up of the sinuses, which often become infected.

It is not always possible to distinguish between a runny nose (rhinitis) and a sinus infection (sinusitis). In general, one refers to both as rhinosinusitis. In both, the production of viscous mucus causes the activity of the cilia to decrease. The mucociliary clearance (the self-cleaning mechanism for the respiratory mucosa) comes to a standstill. This inflammatory process is the reason for the build-up of secretion and lack of drainage, resulting in blocked sinus cavities.

Acute sinusitis symptoms usually last less than 12 weeks, and the cause is generally a viral infection. When sinusitis is chronic, the inflammatory mucosal thickening often persists despite treatment with antibiotics. Acute rhinosinusitis may develop into a chronic form of rhinosinusitis. The conventional medical approach is to treat the symptoms and signs or to suppress the underlying inflammatory condition. Patients have often been prescribed antibiotics, antihistamine, and sometimes cortisone as well. These methods may interfere with the body’s own ability to heal.

The symptoms of sinusitis significantly reduce quality of life and include:

  • blocked nose
  • facial pressure and pain
  • thin or thick fluid secretions
  • breathing restrictions
  • malaise
  • fever
  • loss of sense of smell.

To prevent worsening of symptoms or secondary severe disease conditions caused by the inflammatory process, take Sinulex® Forte at the onset of symptoms. Consult a medical professional if symptoms last for longer than 7 to 14 days, are unusually severe, or suddenly worsen. Sinulex® Forte may be taken long-term and as a preventative remedy.

What is the difference between a cold and the flu?

The common cold is an acute viral infection that invades the upper respiratory tract. Symptoms include runny or stuffy nose, sneezing, sore throat, coughing, enlarged or painful lymph nodes in the neck and headaches. The common cold has an 18 to 48-hour incubation period and usually runs its course in 4 to 10 days.

The flu (or influenza) is an acute viral infection, more severe than a cold, and has a 48-hour incubation period. Symptoms are of sudden onset and include coughing, chills, fever, headache, fatigue/malaise, and muscle aches and pains. The infection usually resolves in 7 to 10 days but may linger longer.
