The LDM Story

On the eastern slopes of the Sierra-Nevada Mountains grows a very important plant in the Parsley Family. The western Indians have long used this plant to prevent and treat many ailments.

The plant is botanically called Lomatium dissectum, so named because of its long, slender, hollow stem
and its oil producing linear glands in the ripening seeds. The Indians called the medicinal root of this plant “the Dortza”, meaning – “heap powerful medicine.” Particularly, the Washoe Indians collected the root in September and October when the richest supply of oils was concentrated in the large underground root. At least five or six gums, oils and oleoresins are present in the very aromatic root. After collecting the root, they sliced it longitudinally, exposing the volatile oils to the oxidizing (polymerization) effects of the air, which converts the oils to a stabilized resin. The cured root would then be hung to dry from the ceiling of their hogan until it was needed.

During the flu pandemic of 1917-1918, the root came into extensive use by the two Washoe Indian bands near Carson City, Nevada. Dr. E.T. Krebs Sr., the contract physician who was assigned by the U.S. government to the Washoe Indians, was dumbfounded to find that the two groups of Indians were free from respiratory illness and that no deaths had been attributed to the in influenza “bug.” This was especially amazing because both Indians and white people were “dying like flies” throughout the entire region, the nation and the world. Spotting the dried root hanging from their hogans, Dr. Krebs asked what it was and what its use was. He was told it was “heap powerful medicine,” and that it was used to prevent colds and the flu. He asked if he could try this medicine on some of his white patients and, after making a crude preparation and giving it to his non-Indian patients in San Francisco, he said, “They just stopped dying.”

How it works

Scientific investigation of the plant reveals that the volatile oil factions in the root contain the anti-viral/ antibiotic ingredient. Also present are powerful anti-bacterial/anti-fungal properties. The Lomatium dissectum extract has a viro-static effect, meaning that it stops the growth of all viruses, bacteria and fungus in the body so that the body’s natural immune system can eliminate the lethal micro-organisms without harming the ones necessary to good health. The effectiveness of Lomatium dissectum in eliminating infections and restoring health is commensurate with an individuals’ natural immune system.


Extensive work has been done by over five universities on Lomatium dissectum. It is a powerful, non-toxic, viro-static against flu viruses, the trachoma virus, the Lansing Polio viruses, and numerous other viruses. By 1944, the Journal of Bacteriology reported, “The anti-biotic activity of oil factions separated from the root of Lomatium dissectum was determined on 62 strains and species of bacteria, molds, and fungi. The heat-stable active agent was bactericidal for gram- positive bacteria at 10-4 dilutions and at 10-3 for gram-negative bacteria.” (Journal of Bacteriology, Vol. 55 No. 5 May 1944)

About the time this report was published, ‘miracle’ sulfa drugs began to be widely promoted. In the interest of being ‘modern,’ no one wanted to use an old Indian remedy. With renewed interest in some natural remedies, Dr. Krebs Jr. passed on the extracting techniques developed by his father to Dr. Max Barlow. The extract is marketed today in an alcohol-based tincture as MD – Microbial Defense.

Today’s Use

Barlow Herbal Specialties receives reports from those using LDM of an approximately 95% success rate. This magnificent product is currently being used in several cancer clinics (mostly in Mexico) with dramatic results for clearing infection in cancer patients. The patients are given 3 to 5 drops sublingually 4 to 8 times a day for 10 to 14 days. A Montana doctor writes, ‘I would not be without this product – especially for my patients with viral infections.’


Since MD – Microbial Defense is viro-static, the dosage depends upon the strength (or weakness) of the body’s natural immune system. MD – Microbial Defense is completely natural and non-toxic; therefore, the dosage may be safely increased until it takes effect. For normal use, 1 capsule 3 times a day is recommended. If using liquid, 1/3 of a dropper taken orally or mixed in water or juice, two to three times a day will combat respiratory infections as well as the flu and colds. The same amount gargled (and swallowed) will clear a strep throat almost immediately. A drop or two should be applied topically for infected sores three to four times a day.

As the above quote from the Journal of Bacteriology indicates, Lomatium dissectum is also effective against molds and fungi. As a result, many of Barlow Herbal users are seeing great results in fighting Candida albicans with our extract (when taken orally). When mixed with a douche, LDM (MD – Microbial Defense) will clear up most yeast infections. A drop between the toes will eradicate athlete’s foot.

MD – Microbial Defense (LDM) may be taken as a preventative against viral infections or solely during high-risk periods. This wonder drug of nature inhibits growth and reproduction of viral organisms, rendering them inactive, thus enabling white blood cells to do their job.

Adults: 1 capsule 3 times per day or 3 to 10 drops, 3 to 5 times daily, or more. It is suggested to begin with a low dosage and frequency and gradually increase. Keep dosage low for the first 7 days and then increase as needed. Children: 3 to 4 drops, 4 to 6 times daily. It is also recommended to gradually increase quantity and frequency. 1 to 2 drops for babies added to water or juice.

It should be noted that some people may experience a one-time detox rash from an oil faction found in Lomatium dissectum; as is possible from contact with any plant. The rash ranges from mild to full body and can be itchy and uncomfortable. Such a reaction can be quickly overcome by taking Dandelion Root, Vitamin C, and Pantothenic Acid. Two days of only fresh juices has been found to speed up the detox process. The addition of fresh squeezed wheat grass juice is also extremely helpful. One can discontinue use of MD – Microbial Defense (LDM) temporarily.

Lomatium Dissectum Rash Information

If you are new to LDM (Lomatium dissectum) you could develop a one-time detox rash. This rash can cover a small percentage of the body or be full body. It can be itchy, swollen and very uncomfortable and sometimes accompanied by a fever and purple welts. If you have never used Lomatium we recommend taking Dandelion root either in liquid or capsule form for a few days prior to taking Lomatium and continue taking Dandelion root for the first week of taking Lomatium. This seems to help the body process the detox reaction and in most cases, lessen the chances of a rash, the severity of the rash in people who still get it and in some cases – prevent it altogether.

You should always start with a very small dosage when taking Lomatium for the first time. 
A very small dosage of Lomatium Dissectium (LDM) would be 1 capsule per day for the first week or 5-10 drops of liquid in water once a day for the first week for adults. You can even start with 1-5 drops once a day for the first week. And in capsule form (MD – Microbial Defense) one capsule once a day for the first week is considered a small dosage. It is easier to start with a smaller dosage when Lomatium is in liquid form.

Dandelion Root is in Munity Boost, the recommended product to eliminate the rash.

Such a reaction can be quickly overcome by taking Dandelion Root, Vitamin C, and Pantothenic Acid (Vitamin B-5). Two to three days of only fresh juices has been found to speed up the detox process. The addition of fresh squeezed wheat grass juice is also extremely helpful. A soothing Epson salt bath and calamine lotion will usually provide relief from itching. One can discontinue use of LDM temporarily while the rash is running its course. It is very rare to get the rash a second time. When taking LDM or MD – Microbial Defense for the first time it is recommended to start slow for the first 7 days as the rash usually takes between 5 and 7 days to show up and about the same amount of time for the rash to go away.
