Sinus Clear


Ridgecrest Herbals

SinusClear™ is a unique combination of natural ingredients designed to help support the nasal passages. The ingredients in SinusClear have been shown to:

Maintain healthy sinus passages*

Help balance moisture*

Support immune function*

Year-round, sinus interruptions can drop in on you at any time like Debra from HR catching you on Facebook. Interference to clear sinuses can also be caused by normal, external exposure to allergens, dust, smoke, chemicals - even pregnancy. RidgeCrest Herbals' SinusClear is specially formulated to help support the body's ability to keep nasal passages and airways clear. It includes mullein, stinging nettle, and rooibos leaf, all thought to support your body's natural state, free from excess inflammation. Other ingredients support free breathing. Regardless of the cause, SinusClear can help you get back to feeling and sounding more like yourself and less like Fran Drescher.



An enzyme found in pineapple, bromelain has been extensively studied by scientists and found effective for a number of different uses, especially its potential to help support the body's natural, healthy state free from excess inflammation.

Mormon Tea Leaf

Despite its name evoking images of the Western US, this plant is found throughout much of the world. Some strains of the natural plant have been shown to contain alkaloids that help support the body's ability to manage healthy mucus levels.

Mullein Leaf

This herb has been used in various global traditions, and each one uses it to soothe the respiratory tract. Whether applied as a warm poultice, taken as a tea or infused in a steam bath, the goal to manage airway health has always been the same. It was also used to ward of Native American spirits, as a dye for Roman women's clothing, and as a wick for lamps in ancient Greece.

Astragalus Root

First appearing in the original text of the Divine Husbandman, astragalus root is one of the 50 core herbs in TCM. Adopted into western culture as a supplement, it is often used to aid sleep, boost energy, and promote a healthy libido. It is also often used to support effective urine flow, promote clear breathing, and help sustain a positive metabolism.

Olive Leaf Extract

Native to the Middle East, the olive tree has stood as a symbol in Western culture for thousands of years. Today scientific evidence shows the components of the olive leaf can help support a healthy immune response, and considering the olive trees' well-known ability to resist disease this makes sense. Its leaves are full of antioxidants, which show promise in supporting cardiovascular health as well.

Stinging Nettle Leaf

Woven into fabric during the 15th dynasty in China and a core element of a European fairy tale, the cultural history of nettle is fascinating and far-reaching. Common in herbal medicine throughout the world, today we know it is a rich in multiple vitamins and minerals, as well as 5HTP and an impressive potential to support the body's natural, healthy state free from excess inflammation.

Rosemary Leaf

One of the most fragrant and delicious cooking herbs, rosemary is rich in essential oils and antioxidants, aids the immune system, and helps support the body's natural, healthy state free from excess inflammation.

Yerba Santa Leaf

A plant indigenous to North America, Native Americans introduced its lung-supporting properties to the Spanish in the fifteenth century. Mostly grown in the Western US, it contains glycerides of fatty acids, resin, glucose, chrysoeriol, and more.

Rooibos Leaf

Native to South Africa, rooibos can be prepared in almost every way but is often used as a delicious red tea. It is rich in zinc, calcium, Vitamin C, potassium, and copper, as well as polyphenols. Most importantly, it is a rich source of flavonoids, which support the body's natural, healthy state free from excess inflammation and immune responses in the body.

Eucalyptus Leaf

Rich in essential oils and antibacterial components, the traditional use of eucalyptus spans the globe, from the Aborigines in Australia for wound care to 19th-century British hospitals as a cleaner. Today it is most commonly used because it is rich in eucalyptol, a natural organic compound studies show may act on the nerve receptors in the mucosa of the nose to help promote natural drainage. Eucalyptus also contains flavonoids and polyphenolic acids that have their own health-promoting properties.

Angelica Root

Part of TCM since its beginnings, angelica root has been used for thousands of years to help tonify and invigorate the blood and support comfort. Often considered a woman's herb, it is one of the most widely-used herbs in China. It may help support circulatory function and relaxation of the airways.

Burdock Root

After noticing the way burdock stuck to his clothes, George de Mestral of Switzerland studied the plants and invented the idea of velcro. European folk herbalists used burdock for a number of health concerns, and modern science shows that it is rich in essential fatty acids (including long-chain EFA's, which are somewhat rare) and phytosterols.

Availablend™ Bioavailability Complex

Availablend™ is RidgeCrest Herbals' patented blend containing several ingredients that have been recognized for their digestive and bioavailability-supporting properties. It includes ginger root, black pepper, habanero pepper, and Sichuan pepper.*
