Echinacea tea is an extremely popular remedy that’s said to prevent and shorten the common cold.

Evidence has shown that echinacea may help boost the immune system, which could help the body fight off viruses or infections (33Trusted Source).

Many studies have found that echinacea can shorten the duration of the common cold, lessen the severity of its symptoms or even prevent it (33Trusted Source).

However, results are conflicting, and most studies have not been well designed. This makes it difficult to tell if positive results are due to echinacea or random chance.

Therefore, it’s not possible to say definitively that taking echinacea will help with the common cold.

At the very least, this warm herbal drink may help soothe your sore throat or clear up your stuffy nose if you do feel a cold coming on (34Trusted Source).

SUMMARY:
Echinacea tea is commonly used to prevent or shorten the duration of the common cold. While several studies have found it to be effective for this use, the evidence on the matter is conflicting.

6. Rooibos Tea
Rooibos is an herbal tea that comes from South Africa. It is made from the leaves of the rooibos or red bush plant.

South Africans have historically used it for medicinal purposes, but there is very little scientific research on the topic.

Nevertheless, a few animal and human studies have been conducted. So far, studies have failed to show that it’s effective for allergies and kidney stones (35Trusted Source, 36Trusted Source).

However, one study has shown that rooibos tea may benefit bone health. One test-tube study suggests that rooibos tea, along with green and black tea, might stimulate the cells involved in bone growth and density (37Trusted Source).

The same study found that the teas also lowered markers of inflammation and cell toxicity. The researchers suggested that this might be why drinking tea is associated with higher bone density.

Moreover, preliminary evidence shows that rooibos tea may help prevent heart disease.

One study found that rooibos tea inhibited an enzyme that causes blood vessels to constrict, similarly to how a common blood pressure medication does (38Trusted Source).

Also, another study found that drinking six cups of rooibos tea daily for six weeks lowered blood levels of “bad” LDL cholesterol and fat, while increasing “good” HDL cholesterol (39Trusted Source).

Much more research is needed to confirm these effects and discover any further benefits. However, the preliminary evidence shows promise.
