Dr. Linda Page, traditional naturopath, and world-renowned herbalist, founded Crystal Star Herbal Nutrition in 1978 and since that time has developed dozens of herbal healing formulas. In 1996, Dr. Page received six of the first-ever United States Patents for herbal supplements for her female hormone-balancing formulas. Three of these formulas remain top-sellers today: Est-Aid™ (now ESTRO-G Balance), Women's Best Friend™, Female Harmony™.
Herbs support the normal functioning of body systems. They contain bioavailable nutrients and therapeutic constituents (such as volatile oils, steroidal saponins, and antioxidants) that the body uses to support its own natural balance. Whole herb blends have been used safely and effectively for centuries and are increasingly supported by Western clinical research.
We receive this question all the time, and yes, our formulas can be used together. In fact, many customers use a variety of our products regularly. We recommend using 2-4 Crystal Star formulas at a time for the best results.
Crystal Star products can be used with many other types of supplements such as multivitamins, minerals like calcium or magnesium, amino acids, and collagen. There are very few known interactions between herbs and other supplements.
Using whole herb blends offers significant benefits compared to concentrated herbs. Here are a few reasons why:
Herbal blends generally use whole herbs. This means the whole plant or the part of the plant that’s used in the formula (a.k.a. herb constituent) has not been altered beyond basic preparation techniques (dried, powdered, extracted).
Whole herbs are foods that offer specific nutrients that your body can use to nourish and balance itself.
An herbal blend supports multiple body systems. We include herbs to address primary and secondary concerns, as well as the catalytic herbs that help deliver these nutrients to the body. Using an herbal blend also helps minimize potential side effects or interactions associated with high doses of single herbs or concentrated herbal extracts.
We believe that herbal quality and the combinations are the most important features of our formulas, so yes, they can be effective. Our formulas encourage your body to rebalance and regulate itself. Expertly blended whole herbs can do this over time for potent but gentle results.
We cannot guarantee product potency after expiration. There are many variables involved that are out of our control after shipment, including storage conditions, exposure to heat, light or humidity. However, for most whole herb blends (caps, tea, or extracts): If the product is kept securely closed and in a cool, dry environment, it can often be potent for up to 1-2 years after the expiration date.
While drug herb interactions are rare, they do happen. It’s important to share any supplements you’re using with a trusted healthcare professional if you’re using medications or have a medical condition.
Many customers like our Muscle Relax product for these types of concerns. Herbs in Muscle Relax help to ease occasional cramps, soreness, spasms, and minor back and neck pain. It’s also a great choice to help muscles relax after exercise. You can use it daily as directed.
Adrenal Support, Male Performance, Men’s Libido, Women’s Libido and Ocean Minerals are our best choices for energy support. These products are high in bioavailable nutrients that encourage and promote the natural function of the endocrine system. They provide a clean energy boost without harsh stimulants.
For people with exhausted adrenals (that’s most of us today), Adrenal Support is our go-to for reinvigorating the body while counteracting stress that worsens fatigue.
If you’re more concerned with concentration and mental energy, Focus caps can give you the support you need.
We recommend Relax caps or Adrenal Support for stress and anxiety. They contain herbal nervines which have been used for centuries to encourage normal nervous system functioning. They can also be used as-needed to ease chronic or acute stress symptoms.
We suggest following an herbal cleanse 2-4 times a year for the best results. If you want to follow multiple cleanses (like liver and colon), we recommend giving your body a break of one month between your programs. To increase the positive results, drink plenty of water and follow a whole foods diet. Long, unsupervised cleanses can deplete the body of critical nutrients. Read more at our wellness blog here.
The herbs in this blend (like peppermint) are carminatives that help to ease gas and bloating. They may be taken with or without food to ease mild digestive symptoms and promote normal digestive function.
Our Kidney Care (formerly Stone Defense) product is a great option for general kidney wellness. It includes herbs like chamomile, stone root, and hydrangea, which promote natural cleansing and fluid balance. For best results, drink plenty of water and follow a plant-based diet. If you have kidney disease or kidney stones, ask a healthcare professional if herbs are appropriate for you.
Herbs are not able to address all types of parasites, but can be helpful for some. Always check with your doctor first if you suspect you have a parasite infection. Our Para Purge product can be used for cleansing support one-to-three times a year. It is a popular choice, especially for people who travel a lot.
St. John’s wort is known for its mood-elevating properties, but it can interfere with many prescription medications such as antidepressants, antibiotics, birth control pills, blood pressure medication, organ transplant medication, HIV medication, anticonvulsants, blood thinners, and asthma medication. We suggest any person taking prescription drugs or preparing for surgery consult with their physician before using St. John's wort or blends containing St. John’s wort. Crystal Star formulas that contain small-to-moderate amounts of St. John’s wort include Mood Lift, Crave Eze, Tummy Control, Muscle Relax, Thin After 40, and Fat & Sugar Detox.
Licorice is a widely studied natural antiviral, female hormone balancer, and adaptogenic herb that can help address stress and adrenal fatigue. It’s also commonly used as a complementary herb in modest amounts in both Western and Eastern herbal blends. However, you should avoid licorice if you have high blood pressure or are on blood pressure drugs. In very high doses, the licorice constituent glycyrrhizin can cause elevated blood pressure. Licorice is also not advised for pregnant women or people with a history of renal failure, as well as people who are on heart medication or steroid drugs.
Crystal Star formulas that contain small amounts of licorice include Adrenal Support, Beautiful Skin, Candida Balance, EstroG Balance, Female Harmony, Fibro Defense, Focus, GI Support, Herp Defense, Inflama Relief, Kidney Care, Prostate Support, Tummy Control and Women's Dryness Extract.
Oatstraw (like oats) does not contain gluten like other grains such as wheat, barley, and rye. It does however contain a protein known as avenin that is well tolerated by most people with Celiac disease and those with gluten intolerance or sensitivity. That said, avenin can bother a small minority of people with Celiac disease. For more information, https://www.herbal-supplement-resource.com/oat-straw.html
Our products are currently sold in natural food stores across the U.S. and are available for worldwide shipping at iHerb.com. We are looking to add other countries so connect with us on social media, where we will post any news about upcoming global shipping.
We do not currently ship directly to Canada but are looking to add that option soon. You can buy our products on iHerb.com. Please follow us on social media where we’ll post any news about coming to Canada.
Directions (or Suggested Use) are included on product labels and on product pages online. Our expert formulators develop recommendations based on the principles of traditional herbalism. Suggested use for most supplements sold in the U.S. are based on a 150 pound adult, so feel free to make minor adjustments to account for weight. However, we suggest doing this only with guidance from an experienced herbalist.
Unless otherwise specified on the directions on the label, you can take Crystal Star products with food or on an empty stomach. For ease of digestion, many customers take our products with food.
Our labels provide Suggested Use information on how long to use each product. Many formulas work within a few days to a week, while others can take several months. Some formulas can also be taken as needed for maintenance.
Yes, there is a difference. These herbs work well together to support men’s health. They mainly differ in the proprietary blend and amount used in the most effective combination to balance the body naturally.
It’s safe to use both products together, but we recommend starting with one. If, after one month you feel that you could use additional support, feel free to add the second product to your routine.
Unless specifically stated on the product label, most Crystal Star products are not for use during pregnancy. Blends like Female Harmony and Conceptions Tea can be used for preconception, but should be discontinued when you become pregnant. Please note that when you conceive, you should begin to receive prenatal care and work with an experienced doctor or midwife.
In the case of fibroids, we suggest you first consult with a health professional to determine the treatment that's right for you. Very large fibroids or multiple fibroids may require a medical approach. However, whole-herb combinations can be helpful for some women because they can support healthy uterine tissue.
Here's our suggested program: Take Women's Best Friend™ during your period then switch to Fibro Defense™ in-between your period. Sticking to a plant-based diet also eases symptoms for many women. For more information check out our blog Don't Wait Out Uterine Fibroids.
We recommend you take Fibro Defense before and after your period, 2 capsules twice a day for two-to-four months. While on your period, you may switch Women's Best Friend to help ease discomfort. For best results, rotate these two products for three months. You may see a noticeable difference within three months, but some women need to take it for five or six months. After you have taken these products for at least three full cycles, we suggest you follow this protocol for one cycle every 3-4 months for maintenance.
In our rebranding efforts, we set out to make our product line easier for everyone to understand and to use. We spent over a year reviewing every product and label with our herbalist so that we were clearly communicating exactly what each product does, when you should take them, and how much you should take.
As one of our oldest and most popular products, Women’s Best Friend has undergone several changes over the years. Women’s Best Friend was designed by Dr. Linda Page as a menstrual support product but, somewhere over the course of 40 years and several owners, the suggested use became more generic. After reviewing the properties of each ingredient, we decided to revise the suggested use directions in order to maximize the formula’s efficacy and honor its original intent.
Our mission is to ensure gentle but powerful results at the best value possible. We are, and have always been, fully committed to providing high-quality products to help you lead your healthiest life.
While it’s true that some herbs like dong quai, red clover, and licorice contain natural phytoestrogens (estrogen-like compounds), there is no credible evidence that moderate intake of these herbs in their whole form will increase your risk for estrogen driven disease, like breast cancer.
Research suggests phytoestrogen activity from whole herbs is very mild. In fact, some epidemiological studies have actually found a connection between high intake of dietary phytoestrogens and lower rates of certain cancers, cardiovascular problems, and menopausal symptoms.
Still, if you have an estrogen-based health problem, it’s a good idea to talk to your doctor before using herbs that can affect hormone balance. Other products on the market use concentrated sources of phytoestrogens, or may be otherwise inappropriate for your unique health needs.

We are proud of our legacy, our unique, blended formulas, and our integrity and commitment to help you achieve balance through holistic remedies. Every Crystal Star supplement is specially formulated and thoroughly tested for safety and efficacy. Our time-tested formulas have a low probability of side-effects or interactions. Whole herbs in Crystal Star formulas are processed by the body in the same way that foods are. Because whole herbs act as therapeutic foods they are much less likely to produce side effects or cause interactions than more potent preparations or concentrated herbs. Further, to verify authenticity, each botanical ingredient is tested upon arrival for identity, potency, and purity. We test for microbes, contaminants, and heavy metals. Following production, each formula is given one final test to ensure quality assurance. Every lot also undergoes analytical testing by a 3rd party to verify consistency for every formula.
Proposition 65 (a.k.a. Prop 65) is a California law originally designed to protect both citizens of California and the state’s drinking water from exposure to a wide range of potentially harmful synthetic and natural substances.
Prop 65 applies to metals such as arsenic, cadmium, lead, and mercury, which Prop 65 defines as reproductive toxins. Prop 65 also identifies arsenic, lead, and cadmium as carcinogens. These metals are found in soils all over the world and are both naturally occurring and a byproduct of human agriculture and industry over the centuries.
Because these metals contaminate soil worldwide, there’s a chance that all plants--even organically farmed ones--may be exposed to them as they grow. For that reason, companies that sell products manufactured from plants (including herbs) must test for toxins and include a Prop 65 disclaimer on their labels regardless of what these results show.
In compliance with Prop 65, Crystal Star has listed this warning on our product labels. This does not mean that the product is unsafe. For specific information on Prop 65 please visit: www.p65warnings.ca.gov/
Kava kava root has been shown to have calming, muscle-relaxing and stress-reducing properties and may help with anxiety and sleep. Though kava can be used safely in moderate doses, excessive use may be harmful, particularly if the kava is in the form of a concentrated, standardized extract. Additionally, some standardized extracts or lower-quality products may contain kava stems or leaves, which have been linked to liver problems. The majority of people can enjoy the benefits of kava root taken in moderation. We don’t recommend any form of kava for people with a history of alcoholism, pre-existing liver problems, or who are taking prescription drugs.
Cascara is considered by most herbalists to be a non-habit-forming laxative which can be used safely as directed as needed for digestion support. Do not use if you have or develop diarrhea, loose stools, or abdominal pain because Cascara Sagrada Bark may worsen these conditions. Cascara sagrada is present in small-to-moderate amounts in our Para Purge formula.
