Heaven Warned of These 3 Plagues—Here’s How to Fight Them
Feb 19, 2025
Marie-Julie Jahenny was warned about coming chastisements—but Heaven didn’t just warn, it also gave remedies. Are you ready? Let’s dive into three prophesied plagues: the herbs to fight them, and how to use them.
Watch the episode below:
Who was Marie-Julie Jahenny?
Marie-Julie Jahenny was a 19th-century French mystic who had incredible visions of Our Lord, Our Lady, and various saints. She lived in a small village in Brittany where she received the stigmata at the age of 23. She survived for years on just the Eucharist and she also had the gift of hierognosis [hiro-nosis], which means that she could tell the difference between a consecrated Eucharistic host and an unconsecrated host, she could tell whether an object had been blessed by a priest or not blessed, and you could show her a relic and she would know whether it was authentic and where it came from without being told.
But what really makes her story interesting—especially for us today—is that she was given numerous prophesies for modern times, and for the end of the world, including remedies for times of chastisement. These remedies are very simple, using common plants that you might even have growing in your own backyard. So today, I’m going to share about these remedies and how to use them. This information I’m about to share is for educational purposes only, and is not meant as a substitute for medical advice. Make sure that you check with a healthcare provider before using herbal remedies, especially if you are pregnant or are on medications.
Remedy #1: Hawthorn
The first remedy uses a very special plant: the hawthorn (Crataegus spp.). Hawthorn grows in temperate regions of Europe, North America, Asia, and North Africa. They are thorny plants with toothed leaves, and can be small shrubs or tall trees. In the spring they have white or pink blossoms, and in the fall they have red berries.
It is believed that Christ’s Crown of Thorns was woven from branches of the hawthorn. There’s also a fascinating legend that one of Jesus’ disciples, St. Joseph of Arimathea, cut a staff from the very same tree that the Roman soldiers used to make the crown of thorns. And after the crucifixion, he sailed to Glastonbury in England, where he stuck this staff into the earth. Miraculously, the staff took root and bloomed. This hawthorn tree became known as the Glastonbury Holy Thorn.
The Holy Thorn miraculously flowered every winter—even though hawthorns are supposed to only bloom in the springtime. This started the tradition of cutting a flowering sprig and sending it to the British Monarch every Christmas. Even after Glastonbury Abbey was brought to ruins during the reign of Elizabeth I, the thorn continued to flower at Christmastime, giving hope to Catholics who viewed the miraculous blooming as a testament to the fact that our faith continues to flourish even in persecution.
The Puritans, on the other hand, hated the thorn, since it was a Catholic symbol, and the Holy Thorn was chopped down and burned during the English Civil War of the 1600s. Fortunately, propagations of the original Holy Thorn survived. One, which was planted on Wearyall Hill, lasted until May of 2019, when it was removed by the land owner and a Conservation Society member who considered the thorn to be “dangerous.” Some holy thorns still survive at the Church of St. John in Glastonbury, which is where the Christmas sprig for the King is now cut from.
Hawthorn is one of the best herbs for the heart. It’s been used for centuries to support cardiovascular health. It works as a cardiac trophorestorative and cardiotonic, meaning it nourishes and strengthens the heart over time. It’s also hypotensive, helping to lower blood pressure, and hypolipidemic, meaning it can reduce cholesterol levels. Its vasodilator properties improve circulation, while its anti-inflammatory and antioxidant properties protect blood vessels from damage. But hawthorn isn’t just about the heart in a physical sense—it’s also a nervine, which means it helps calm the nervous system. This makes it especially helpful for those who experience anxiety or stress, particularly when that stress manifests as heart palpitations or high blood pressure.
In Marie-Julie Jahenny’s revelations, Hawthorne can be used to treat a new illness which will occur in the future. On August 5, 1880, Our Lady said to her:
“There will be a grave illness which human science will not be able to alleviate. This illness will attack firstly the heart, then the spirit, and at the same time, the tongue. It will be horrible. The heat accompanying it will be a devouring fire insupportable and so intense that the members of the body affected will be red – an unendurable fiery red.”
She goes on to say that the disease has a 7-day incubation period and it will spread rapidly all over the body, causing continual vomiting and nausea. To treat this disease, she says to gather the leaves of the Hawthorn, dried leaves being just as effective as fresh ones. Boil the leaves in water for 14 minutes while covered so that the steam doesn’t escape. You can do this in a covered pot on the stove, but what I like to do is boil the water in a kettle first and then pour that into another container like this little pot. This pot has an infuser inside of it to keep the herbs separate and a lid to keep the steam inside. You can also use just an infuser like this inside a mug and cover it with a lid or a saucer. Our Lady didn’t specify what amount of herbs to use, so I use 2 tsp of herbs to 8 oz of water— that’s the standard that herbalists tend to use. So, after this has been brewing for 14 minutes, your tea is ready to drink. Drink this tea three times a day, as soon as you contract the disease. Our Lady said that it is important to treat the disease promptly at the onset. If the remedy is taken too late, then the affected part of the body will become black with a pale, yellow streak in the middle.
In Marie-Julie’s revelations, Hawthorne can also be used to treat cholera. Cholera is a bacterial infection spread through contaminated water or food and it causes severe watery diarrhea, vomiting, muscle cramps, and dehydration.
A common question I get asked about Hawthorne is how to find it without the flowers. It would be very difficult to find dried Hawthorne leaves without the flowers in them, because Hawthorne leaves are typically harvested in the spring together with the flowers. But that’s ok, because Our Lady didn’t say that you can’t use the flowers. In her message, she says to gather the leaves and not the wood, but she doesn’t say anything about the flowers. Also, just so you know, typically you will find a few twigs mixed in with the leaves and the flowers, but that’s OK too— Our Lady didn’t say the wood was bad, only that the wood isn’t going to help you. It’s the leaves that will help you.
Remedy #2: Violet
This next remedy uses a very common plant, which could be growing as a weed in your own backyard. It’s the violet, and it is probably one of the most useful herbs in my collection. Violets are called “Our Lady’s Modesty” because they are a symbol of the Blessed Virgin Mary’s humility. St. Bernard of Clairvaux used violets to teach the virtue of humility, since violets bloom low to the ground and don’t draw attention to themselves, yet they give off a sweet fragrance.
Violet is a very gentle herb that has been used for centuries across many cultures for a variety of health benefits. It’s known for its cooling and soothing qualities, and is commonly used to help with respiratory issues, like coughs and asthma thanks for its anti-inflammatory, antioxidant and expectorant properties. It’s also great used topically for skin problems like eczema, acne, and wounds. Violet supports the lymphatic system, helping with swollen glands and fibrocystic breasts. It also calms the nervous system, which makes it useful for stress, insomnia, and emotional healing, especially when dealing with grief or anger. Violet is so gentle that it is often used for children with asthma or needing immune support.
St. Hildegard of Bingen, a mystic and Doctor of the Church who wrote extensively on herbal medicine, had a lot to say about violets. She used them in salves and pultices for cataracts, palsy, headaches, and ulcers. She says to eat violets as a salad with plantain, savory and vinegar if you have tertian fevers (that is a type of fever that recurs every third day, typically caused by the malaria parasite). She also recommends that anyone who suffers from depression along with ailing lungs should cook violets in wine, strain them out, add a pinch of galangal (that’s a spice related to turmeric and ginger), add a pinch of licorice root powder, and drink this spiced wine to make you feel happy again and heal your lungs.
Marie-Julie Jahenny’s revelations simply state:
“For unknown fevers, the humble violet, the perfume and virtue of humility will have effect.”
I’m assuming that she is referring to an infusion here, just like with Hawthorn. So the usual dosage would be one to two teaspoons of dried violet herb in 8 oz boiling water, brewed for 5-10 minutes, and drank three times per day. I will give this tea to my kids with some honey if they have a fever, or if they have a respiratory illness.
Remedy #3: St John’s Herb
The last of Marie-Julie’s herbal remedies for times of chastisement uses St. John’s Herb, and the scientific name is Glechoma hederacea. NOT to be confused with St. John’s Wort, which is a completely different species of plant. There has been some confusion about this because some translations of Marie-Julie’s revelations say “St John’s Wort”, however the species name given is Glechoma hederacea. Glechoma hederacea is common ground ivy, also known as Creeping Charlie. Like violet, you may have this growing as a weed in your own yard, if you live in a northern-temperate region of the U.S., Eurasia or Canada. It is a member of the mint family, and has round or kidney shaped leaves with scalloped edges and blueish purplish flowers.
St. John’s Herb has traditionally been used to support the lungs and the respiratory system. It acts as an anti-catarrhal, expectorant, and pectorant, helping to clear congestion and soothe coughs. It is anti-inflammatory, antioxidant, and astringent, making it useful for strengthening tissues and reducing irritation. It is also known for aiding digestion. It works as a digestive, stomachic, and tonic, meaning it stimulates appetite, supports gut health, and promotes overall well-being. It also has diuretic and depurative properties, helping the body eliminate toxins. Historically, it was a remedy for scurvy, due to its vitamin C content. Women have used it to encourage menstrual flow, and it’s even been applied topically to help heal wounds. It can also be used to induce nasal discharge and clear blocked sinuses. However, do NOT use this herb if you are pregnant or trying to become pregnant because it may cause miscarriage.
St. Hildegard recommends ground ivy for various illnesses of the head, for chest pain, and for revitalizing the body to speed up recovery. Marie-Julie’s revelations say:
“You will take an infusion of St John’s Herb especially during crisis, sufferings of the chest and violent headaches.”
No other instructions are given, but the typical dosage would be 2 tsp per 8 oz of water, steeped in just boiled water for 5-10 minutes, and drank three times per day.
Other Remedies
Before I wrap up this episode, there are a few other remedies of Marie-Julie’s that are worth saving for the future. So grab a notebook because you might want to write these down. For unknown illnesses, you’re going to need a medal of the Divine Heart of Jesus and a medal of the Cross. If you have a scapular medal [like this one], then you may already have these two medals in one, because the scapular should have an image of the Sacred Heart of Jesus, and many scapular medals are in the shape of a cross because they are four-way like this one which has not only the scapular but also the miraculous medal, the St Joseph medal, and the St Christopher medal. You can find many vintage four-way scapular medals like this one on Etsy. So, what you do is you dip the two images—the Sacred Heart and the Cross—into your water before drinking it. Jesus said to Marie-Julie:
“You will drink this water that is twice blessed and twice purified. A single drop in your food, a tiny drop will be sufficient to keep away not just the scourge, but the scourges of my Justice. You will give a drop of this water to the poor souls struck by the scourges of unknown illnesses.”
For fear, you need a picture of Our Lady or a Miraculous Medal. Again, if you have a four-way medal, then you already have a Miraculous Medal. So Jesus says:
“To dissipate all fear and all fright you will touch your foreheads with the picture or the gentle medal of Mary Immaculate. Your spirits will remain calm. Your intelligence will not fear the approach of the terror of men. They will not feel the effects of my Great Justice.”
Then finally, Marie-Julie’s revelations mention a “mortal plague.” There’s not a lot of detail given about it, but by its name I’m assuming that this is a deadly disease. She says there will be only one remedy for protection from this plague. It will be to write on very thin paper: “Oh Jesus, Conqueror of Death, Save Us. O Crux ave.” Then you roll up this paper into a little ball and swallow it like a pill. I’d suggest using an ultra fine tip, food safe, pen with edible ink— these are usually used for cake decorating. That way, you’re not swallowing anything toxic. You can find these one Amazon— I’ll link one in the description.
Remember, even during tough times, we can always count on God to know what’s best for us, so even when we get struck with illness or with hardships, we can trust Him that it’s all according to his plan. It’s comforting to know that there are remedies which God placed in nature to help us deal with these things, but it’s also important to remember that God may still allow us to get sick, and that’s OK. A friend of mine with M.S. said that once when she was struggling to walk and she was grumbling about it, she heard a voice say very clearly and distinctly that every step she takes while complaining, a soul could be lost. So perhaps the most important thing we can remember is to offer all of our sufferings to God without complaint, so that He can use them to save souls.
