After beginning to take Ayurveda seriously, you can have a small shelf of herbs: Ashwagandha for stress, Shatavari for hormonal balance, Shilajit for energy, Triphala for digestion and so on. It just naturally occurs to me, and it doesn't get talked about enough: how safe is it to stack multiple of these together, or could there be detrimental interactions, or diminishing returns, from taking too many at once?

This article analyzes traditional Ayurvedic concepts on the use of herbs in combinations, what science says about that, and how to develop a multi-herb regimen without trial and error.

How Ayurveda Traditionally Views Herb Combinations

Contrary to popular belief, Ayurveda never considered herbs as stand-alone, single combination remedies to be taken individually. In classical Ayurvedic medicine, multiple herbs have always been deliberately combined, and it is recognized that some herbs have synergistic properties that can intensify their individual effect or neutralize possibly overpowering or individual properties.

Multiple herbs in combination formulations have been a tradition in Ayurveda so this is not a risk in itself. It is actually very much on the lines of the way Ayurveda has been practiced all along – if it's thoughtfully done – not randomly.

What makes a Herb Combination Safe vs. Risky

When it comes to safety, there's no simple yes or no answer, but there are several things to consider:

Combining more than one herb that has a strong effect, like several herbs that are all laxatives, can create a stronger effect than what might feel comfortable or safe, even if each herb is comfortable/safe alone.
Multiple herbs in the same direction on the same dosha can create cumulative effects, Ayurveda classifies herbs according to their effects on vata, pitta, and kapha and combining several herbs that have a strong effect on the same dosha in the same direction will push the dosha further out of balance than returning it.
As per the Ayurveda principle of personalization, the combination of two or more herbs may be effective for one person's prakriti (constitution) but not for the other, as in, don't just take five herbs and expect them to work for you.
High dosages of less than safe herbs combined at the same time can be more difficult to break down by the body, especially the liver and kidneys which are responsible for metabolizing plant compounds.

Common Combinations that are considered safe to use

These are a few combinations that have traditionally been used together and should be safe to use together:

Ashwagandha and Shatavari: The two herbs are traditionally considered complementary in action, and are often used together to support overall vitality and hormonal balance, especially during menopause.
Shilajit and Ashwagandha: These two herbs are often paired together for strength, stamina and energy, because they act in somewhat different traditional ways and yet for a very similar purpose.
Triphala along with digestive herbs such as ginger: Frequently combined to provide assistance for digestion, each herb plays complementary roles in different aspects of digestion.
Brahmi and Ashwagandha: Often used together in the context of stress resilience and cognitive clarity, as they target different, yet related, areas of mental health.

The combinations that are effective are effective, in part, because they were formulated with an awareness of interactions between the herbs, not just put together randomly.

Combinations that require more attention.

While there are lots of cases where it's safe to take supplements together, some require specific attention:

Using several sedative or calming herbs as a combination: Several herbs with strong calming or sedative effects may cause greater drowsiness than you expect when used in combination.
Multiple herbs with strong detoxifying or laxative properties together: Can cause too much digestive action, dehydration, or electrolyte imbalance, if not using these herbs with care.
Blood sugar or blood pressure herbs: People who are already taking medications for these conditions should be careful when using several herbs that can also affect blood sugar or blood pressure, and should talk to their doctors about how long it takes before the herbs start to work.
If you are already taking several herbs and trying to add another one: This will make it more difficult to determine which herb is responsible for an unexpected reaction.

These are practical guidelines for combining ayurvedic supplements.

When creating a multi-herb Ayurvedic regimen, there are a few practical basic rules to avoid getting too much out of your head:

Start one herb at a time: If you're starting something new, add one herb at a time and see how your body reacts over at least a week or two, before adding on another.
Make it easy to keep one easy record: Take note of what you're using, when, and what effects you notice, and it will be much easier to see what is working well and what may be problematic.
Select high-quality, well-formulated products: Standardized, quality-tested, and from a trusted source (like Varah Healthcare) reduces the risk of the uncertainty associated with supplementing with herbs that may have inconsistent potency or purity.
Consider combination formulations designed together: Rather than mixing several separate single-herb products, a thoughtfully formulated combination product designed by someone with genuine Ayurvedic formulation expertise can offer a more balanced, tested approach than DIY stacking.
Review regularly: As needs and body composition change over time, the right combination of supplements may change, so it's important to review them periodically to make sure the combination is still right for you given your current needs.

When to see an Ayurvedic Practitioner or doctor

A few scenarios call for expert advice before taking more than one herb: when taking a prescription for some health condition, especially one that affects blood sugar, blood pressure, or blood-thinning properties; when pregnant or breastfeeding; when a person has an existing liver or kidney disease, or another chronic health condition; and when unsure how multiple herbs might interact, due to specific health factors. But it is not something that a qualified ayurvedic practitioner or doctor can guess, it is possible to create only a combination suitable for a particular constitution and health status.

Conclusion

The use of more than one Ayurvedic supplement is not a problem in itself, and in fact the use of herbal formulation is the way that Ayurveda has traditionally been used for centuries. The secret is to select complimentary, not redundant, combinations, add the herbs in slowly and monitor how your body reacts. When using herbs with prescription medications or current medical conditions, and when deciding on the quality and formulation of products, you are ensuring that you are creating a regimen that will work for you and not create additional risk.

Frequently Asked Questions

Q: Can 3+ Ayurvedic supplements be taken together?

A: It may be, as long as they are carefully selected for their complementary effects instead of overlapping, and preferably not all at once. For more complicated combinations, it is best to consult an Ayurvedic practitioner.

Q: Are there any guidelines for when to take all of my supplements?

A: Not necessarily. Certain herbs are traditionally taken at certain times, e.g. shilajit in the morning and soothing herbs in the evening; it is better to take these herbs at a particular time instead of having them all together.

Q: Can combining Ayurvedic supplements interfere with prescription medication?

A: It's possible, particularly with herbs that influence blood sugar, blood pressure, or blood clotting. Please be aware that Ayurvedic supplements should never be taken in conjunction with prescription drugs, treatment or medication, without consulting your doctor first.

Q: Should I use a combination product already formulated or make my own?

A: Pre-formulated combinations from a trusted brand such as Varah are typically well-balanced with dosed and coordinated herb selections and can eliminate some of the trial and error that happens when you mix different brands.
