Scientists at the Rider Boskovic Centre in Zagreb, Croatia, formulated a natural, activated astragalus root extract known as Lectranal. This herbal medicine has been rigorously trialed and tested and found to be able to calm hypersensitive noses.
The results of this research were published in the journal Phytotherapy Research in 2010. Treatment with Lectranal resulted in an overall improvement of nasal allergies by over 70% after two months of treatment. Unlike other general, non-specific therapies, Lectranal aims precisely at the hypersensitive nature of the immune system, which triggers nasal symptoms. With Lectranal, the immune system is guided not to over react, instead perform normally as it should.
Essentially, Lectranal helps to calm hypersensitive immune systems from getting out-of-control every time it meets an allergen such as dust or temperature changes. As it does this, the patient’s nose will also not hyper-react when in an air-conditioned room. Lectranal works differently from drugs such as antihistamines, which help dry a runny nose but not aid with the root of the problem. By directing the immune system towards normal response and imparting a memory to help it recognise harmless allergens, Lectranal prevents the nose from being too sensitive.
