Not always. For those people who have poor kidney function, the answer is simple; some are ok, some are not, and only your nephrologist can give permission. Just because something is natural does not mean that it is safe.

We can analyze this in a virtual cup of chai. Shall we?

Why "Natural" Is Not a Magic Bullet

Your kidneys are the bouncers of your body, filtering everything that is in there. When healthy, your kidneys will process anything that comes your way. In case of malfunction, any extra ingredient becomes one extra guest for them to check at the door.

Herbs are active compounds. Some of them affect blood pressure, others affect potassium, and others irritate the kidneys directly. Furthermore, supplements are not as strictly regulated as prescription drugs. This means that the label of the supplement does not guarantee that the bottle contains exactly what is printed on the label.

What do the studies say?

In Belgium, in the early 1990s, women who were taking a slimming regimen with Aristolochia suffered from rapid development of severe renal failure. Vanherweghem et al. published their findings in The Lancet (1993).

In the American Journal of Kidney Diseases, there is a review which states that many herbal medicines can lead to damage to the kidneys or worsen their disease in people with pre-existing kidney disease. Another report from the American Journal of Kidney Diseases shows that noni juice can lead to dangerously high potassium levels in the organism. It's funny to think that this healthy drink has such side effects.

Special Attention Herbs

  • Aristolochia (birthwort): Can cause irreversible damage to the kidneys
  • Licorice root can increase your blood pressure and disturb the potassium balance.
  • Noni juice and alfalfa: these juices are rich in potassium and thus risky for people with impaired kidney function
  • Star fruit: a known troublemaker for people with advanced disease
  • Herbal detox blends: mystery ingredients, mystery outcomes

Well, Is There Any Safe Option?

People love googling the herbs that are useful for kidneys. Some names that come to mind immediately are punarnava, gokshura, and varuna. Some lab and clinical work exists, but it is not very large-scale, so you can only talk about "promising" herbs instead of proven ones.

The same can be said about the best herbal supplements for kidneys. The choice of the best one will depend on the stage of kidney disease, lab results, and other medications that you are taking. The one that works for your neighbor's cousin might not work for you.

What is Ayurveda?

Traditional Ayurvedic kidney disease treatment looks at the whole person as a whole, taking into account his diet, digestion, lifestyle and herbs together. Many people decide to receive natural treatment of kidney disease alongside their regular therapy, and in this case, it makes a lot of sense. The idea is to supplement, and not replace, the therapies that have already been recommended.

If you are interested in this type of treatment, find practitioners who ask you to provide your reports and collaborate with your nephrologist. You can visit Karma Ayurveda, which offers renal treatment that is completely natural and almost free from side effects. Naturally, you should consult with your doctor before starting anything.

Golden Rules

  • Tell every doctor about every supplement that you are taking
  • Never use an herb without having your latest blood and potassium tests and the reports
  • Do not purchase products that have no ingredients list and batch number.
  • Contact your doctor immediately and stop taking this medication if you notice swelling, decreased urine, or sudden fatigue

Concluding Remarks

Herbs aren't evil; they aren't heroes. Think of them as guests that have an invitation, an invitation list, and a doctor's check-up. Be slow, be aware, and filters will thank you.

Key Takeaways

  • Natural does not imply a safe use for people with renal impairment
  • Some medicinal herbs may have various risks involved, and Aristolochia, noni, and licorice belong to this category.
  • Research on beneficial herbs is very interesting and important for people's health.
  • Talk with your nephrologist about taking any supplement
  • Choose transparent, reputable products and practices
