Herbal Remedies for High Cholesterol: Key Plant-Based Options
Commonly Studied Herbal Remedies for High Cholesterol
Several herbal remedies have been widely studied for their cholesterol-lowering effects. Guggul (Commiphora mukul), garlic (Allium sativum), and black cumin (Nigella sativa) are among the most researched, with evidence showing moderate reductions in total cholesterol and LDL cholesterol levels. Guggul and garlic, in particular, have shown consistent benefits in multiple clinical trials and systematic reviews, with minimal reported side effects, making them safe options for many people 246.
Other herbs and plant products with evidence for cholesterol reduction include red yeast rice, artichoke (Cynara scolymus), fenugreek, green tea, soy protein, and turmeric (curcumin). These have demonstrated varying degrees of effectiveness in lowering total cholesterol, LDL cholesterol, and triglycerides, while sometimes increasing HDL cholesterol 12368910.
Regional and Traditional Herbal Approaches
Traditional medicine systems, such as Ayurveda and Chinese medicine, have long used herbal remedies for managing high cholesterol. In Ayurveda, guggul, garlic, and black cumin are commonly recommended and supported by clinical evidence . Chinese herbal formulas like Xuezhikang have also shown significant cholesterol-lowering effects in clinical trials, though the quality of evidence varies .
Ethnopharmacological surveys in regions like Morocco and Indonesia highlight the use of plants such as flaxseed (Linum usitatissimum), coriander (Coriandrum sativum), oats (Avena sativa), olive (Olea europaea), walnut (Juglans regia), soybean (Glycine max), rosemary (Rosmarinus officinalis), avocado, soursop, and red dragon fruit. Some of these, like flaxseed, oats, and olive, have also been validated in clinical studies for their cholesterol-lowering properties 57.
Mechanisms and Efficacy of Herbal Remedies
Herbal remedies may lower cholesterol through several mechanisms, including reducing cholesterol absorption, increasing bile acid excretion, and providing antioxidant effects. For example, phytosterols found in plant oils and nuts can block cholesterol absorption in the gut, while compounds in green tea, turmeric, and ginger have antioxidant and anti-inflammatory properties that support heart health 810.
Meta-analyses show that sunflower oil, rice bran oil, phytosterols, green tea, soy protein, nuts (almonds, walnuts, pistachios), and curcumin can all significantly improve lipid profiles, with reductions in total cholesterol, LDL cholesterol, and triglycerides, and increases in HDL cholesterol .
Safety and Considerations
Most herbal remedies for high cholesterol are considered safe when used appropriately, with few reports of serious side effects. However, some herbs, such as guggul and garlic, may cause mild gastrointestinal symptoms or interact with other medications. It is important to consult a healthcare provider before starting any herbal supplement, especially for those already taking cholesterol-lowering drugs or with other health conditions 245910.
Conclusion
A variety of herbal remedies—including guggul, garlic, black cumin, red yeast rice, artichoke, green tea, soy, turmeric, flaxseed, and others—have demonstrated cholesterol-lowering effects in clinical studies. These herbs can be considered as complementary options for managing high cholesterol, especially for those seeking alternatives to conventional medications. However, more high-quality research is needed to confirm their long-term safety and effectiveness, and professional guidance is recommended before use.
