Introduction 

All over the world, tea enthusiasts are seeking new flavors.  Rooibos tea is one such tea. It packs in potential health benefits. This article will give you in-depth insight into rooibos tea. Its origin,  potential health benefits, how to prepare it, its side effects are all discussed here. Besides the known facts, we will also discuss some disputed views and common queries related to this tea. Lastly, we will answer some commonly asked questions regarding this topic.  

What is Rooibos Tea? 

Rooibos tea is a distinctive herbal brew from South Africa. It comes from the Aspalathus linearis shrub. This plant grows in the Western Cape’s Cederberg mountains. The tea gets its reddish-brown hue from an oxidation process. You can also find unoxidized green rooibos tea with a higher antioxidant content. Are you looking for a caffeine-free, low-tannin alternative to black or green tea? Rooibos tea is a caffeine-free, low-tannin alternative to black or green tea.  

Origin and History of Rooibos Tea 

The local Khoisan people of South Africa have been sipping rooibos tea for hundreds of years. In 1772, botanist Carl Thunberg observed that they made a pleasing aromatic drink from Aspalathus linearis leaves. Over time, farmers learned more about cultivating this plant and making it into a health-enriching drink. 

Today, people worldwide relish rooibos tea because it’s healthy and tasty. Its ability to mix well with other flavors has made it popular in unique tea blends globally. 

Since Rooibos tea has no calories, in my opinion, it might be a good beverage choice for anyone attempting to maintain a healthy weight or reduce their weight. A 2014 study found that by raising leptin levels, rooibos tea may potentially help with weight management. A hormone called leptin is believed to help control appetite and let the body know when it has received enough meals. Do not skip exercise and mindful eating while incorporating Rooibos tea in your diet to lose weight.

Nutritional Benefits of Rooibos Tea 

Rooibos tea is a nutritional powerhouse. It’s nutritional contents are discussed below.  

Researchers have found that antioxidants such as aspalathin, which are abundant in Rooibos tea, may help aid in diabetes. Aspalathin stabilised blood sugar levels and decrease insulin resistance in rats with type 2 diabetes, according to a 2009 study. These findings may be encouraging for people with type 2 diabetes. However, talk to your doctor before incorporating excess of Rooibos tea for diabetes.

1. Low in Tannins 

Tannins are natural compounds present in many plant foods. They can hamper iron absorption, especially non-heme iron. Rooibos tea has fewer tannins than black or green tea. So, it’s ideal for those who want mild-tasting tea or are worried about iron intake. 

2. Naturally Caffeine-Free 

Caffeine is present in black tea, green tea, coffee, and more. While low to moderate caffeine intake is safe for most people, too much can cause health issues. T It’s caffeine-free and ideal for those looking to steer clear of or lessen caffeine. 

3. Rich in Antioxidants 

Antioxidants in our body keep cell damage in check. These damages lead to chronic diseases like cancer and heart disease. Rooibos tea is full of antioxidants, especially polyphenols such as aspalathin and nothofagin. These plant compounds neutralize harmful free radicals. 

I have read some research which suggests that using rooibos tea topically may improve skin look by minimising wrinkles. Herbal extract-based gel-based cosmetic blends were compared in a 2010 study. Ginkgo, soybean, and a blend of rooibos tea were the extracts used. The researchers discovered that the tea and rooibos combination worked best for minimising wrinkles. However, larger studies might show the real utility of this tea for skin issues.

Health Benefits of Rooibos Tea 

Rooibos tea may offer many health  benefits. These are discussed below.  

1. May Boost Heart Health 

Drinking rooibos tea could potentially improve heart health. Its antioxidants may help cut down ‘bad’ LDL cholesterol and ramp up ‘good’ HDL cholesterol. Aside from that, it may aid blood pressure management. 

2. Lowering Blood Pressure 

In one study, healthy people showed lower ACE activity 30-60 minutes after drinking rooibos tea. ACE raises blood pressure. While we need more data on this, these findings hint that rooibos tea may support heart function. 

3. Reducing LDL Cholesterol 

In a 2011 study, 40 high-risk adults consumed six cups of rooibos tea per day for six weeks. They noticed lower LDL and higher HDL cholesterol levels. Keeping cholesterol in check is vital in reducing heart problems like heart attacks and strokes. More research is needed to corroborate this effect.  

4. Potential Anticancer effect  

Quercetin and luteolin, two antioxidants in rooibos tea, can kill cancer cells and reduce tumor growth, according to lab studies. However, we still don’t know if rooibos tea consumption can yield similar results in humans. We need larger human trials for that. 

5. Antioxidant Properties 

Rooibos tea is antioxidant-rich. These compounds protect cells from damage that can trigger cancer progression. However, it remains to be seen how far these properties can help reduce cancer in humans. 

6. Anti-inflammatory Effects 

Chronic inflammation triggers many diseases, including cancer. With its high antioxidant content, rooibos tea may combat inflammation and contribute to cancer reduction. More research is needed for a thorough understanding. 

7. Support for Type 2 Diabetes Management 

Rooibos tea can assist diabetic individuals in exercising better blood sugar control and reducing insulin resistance. Animal studies hint that aspalathin , an antioxidant in rooibos tea may help combat high blood sugar levels. Aspalathin could also protect against inflammation arising from high blood sugar. 

8. Balancing Blood Sugar Levels 

Research implies that rooibos tea containing aspalathin may help manage blood sugar and tackle insulin resistance in diabetes patients. We need more extensive human trials to substantiate these findings. 

9. Insulin Resistance Reduction 

Aspalathin might aid in reducing insulin resistance, a vital factor in type 2 diabetes development. Ensuring optimal insulin sensitivity is key to  avoiding diabetes-related problems and good health overall. 

10. Improved Bone Health 

Rooibos tea has compounds that may enhance bone health. While we don’t have enough proof, research suggests that it may impact bone growth and maintenance positively. 

• Minerals for Optimal Bone Health 

Rooibos tea contains trace amounts of fluoride, calcium, and manganese that are vital to bone health. Regular intake of rooibos tea might support bone strength and preservation. We need more research to validate these effects. 

• Estrogenic Activity 

Certain rooibos tea compounds have shown estrogenic activity. This may potentially boost bone health. Estrogen aids in maintaining bone density; higher levels are associated with better bone health. But unfortunately, the data pertaining to this aspect of rooibos tea is limited. 

11. Weight Management 

Rooibos tea has zero calories and certain compounds that may influence appetite regulation. So, it may aid weight management. 

• Appetite Suppression 

A study found that rooibos tea increased leptin levels, a hormone controlling hunger. Drinking this tea may aid in suppressing appetite and supporting weight management. 

• Digestion Boost 

Though proof is limited, rooibos tea’s low tannin content might curb digestive problems often associated with tannin-rich drinks. 

12. Anti-Aging Properties 

Antioxidants in rooibos tea may improve skin health and slow down aging, such as wrinkles. Preliminary animal studies support this. But we must await human studies for firm evidence. 

Although studies have seen beneficial health effects of Rooibos tea, more large-scale human trials are needed to confirm these benefits. 

Preparing Rooibos Tea 

You can savour rooibos tea in many ways. A few methods are discussed below.  

1. Traditional Brewing Method 

For a classic cup of rooibos tea, add boiling water to a teabag or spoonful of loose leaves. Allow it to steep for a minimum of 5 minutes. You can have the tea as is or add milk, plant-based milk, honey, or sugar as required. 

2. Cold Brew Rooibos Tea 

Cold brewing rooibos tea produces a refreshing drink. Mix cold water with rooibos tea leaves or a teabag. Refrigerate for a minimum of 4 hours or overnight. Strain the tea and enjoy it as an iced beverage or mixed with your fruit juice of choice. 

3. Rooibos and Tea Blends 

You can  experiment with mixing rooibos tea with other tea varieties or infusing it with herbs, spices, and fruits. Try adding cinnamon, ginger, mint, or berries to your rooibos tea for an exciting flavourful twist.

Potential Side Effects of Rooibos Tea 

Rooibos tea is considered mostly safe, but certain individuals may face unwanted reactions. These are discussed below.  

1. Allergic Reactions 

Rooibos tea could cause allergies in some people. Symptoms include skin rash, itchiness, or swelling. If you face allergic symptoms, stop drinking rooibos tea. Contact your healthcare provider right away. 

2. Liver Damage 

There have been a few reports linking heavy rooibos tea consumption with liver damage. So, it’s best to consume the tea in moderation. If you see signs of liver problems like jaundice, consult your healthcare provider promptly. 

3. Hormonal Imbalances 

Some compounds in rooibos tea have shown estrogen activity. This could affect hormone-sensitive conditions such as breast cancer. If your condition is hormone-dependent  be careful before consuming rooibos tea. Seek your healthcare provider’s advice in this matter. 

4. Drug Interactions 

Rooibos tea might interact with certain medications. Especially, those that get metabolized by CYP3A enzymes. Always talk to your healthcare provider before making rooibos tea a part of your diet. 

Unverified and Other Reported Benefits 

Rooibos tea consumption is associated with some other potential health benefits. However, the proof supporting these claims is scarce. 

1. Digestive Health 

There are claims that rooibos tea may ease digestive issues like bloating, indigestion, and heartburn. However, more scientific research is required to confirm this.
