Four

Four is an herbal formula designed to nourish and support the respiratory system. It combines four traditional herbs—blessed thistle, catnip, mullein leaf, and yerba santa leaves—that work together to promote free, comfortable breathing.

Each serving provides 740 mg each of blessed thistle aerial parts, catnip leaves, mullein leaf, and yerba santa leaves. These herbs have long been valued in traditional herbalism for their role in supporting bronchial and upper respiratory health, healthy mucus balance, and seasonal respiratory comfort.

Take 2 capsules with a meal twice daily. Each bottle contains 100 capsules, which provides roughly a 25-day supply at the recommended serving.

Four is well suited for adults looking for everyday herbal support for their respiratory system, including lung health and comfortable breathing. As with any supplement, anyone who is pregnant, nursing, or taking medication should check with their healthcare provider before use.

Four focuses on a simple, four-herb Western herbal blend for general respiratory support. If you're looking for different approaches, Bronchial Formula takes an Ayurvedic angle, Breathe Activator TCM draws on Traditional Chinese Medicine, and Seasonal Allergy is formulated specifically with seasonal respiratory comfort in mind. VS-C and the Respiratory System packets offer additional options, so you can choose the formula that best fits your needs.
