If you've been hearing headlines about an intestinal parasite causing explosive diarrhea in Connecticut and other states, here's what you need to know about the symptoms and treatment.
The hallmark symptom of this parasitic infection is explosive, watery diarrhea. The infection is caused by a microscopic protozoan parasite called Cyclospora cayetanensis.
Cyclospora Symptoms
Like most gastrointestinal infections, Cyclospora can cause a number of symptoms, including:
Explosive, watery diarrhea
Gas and bloating
Abdominal cramps
Nausea or vomiting
Fatigue
Body aches and malaise
Fever
Flu-like symptoms
A confirmed infection with Cyclospora is called cyclosporiasis.
Symptoms typically begin about one week after exposure, although it can take roughly two weeks for some people to become sick.
One of the more frustrating characteristics of cyclosporiasis is that symptoms can improve and then return. Without treatment, diarrhea and other symptoms may persist for weeks or even longer.
How Is Cyclospora Diagnosed?
Cyclospora is diagnosed using specialized stool testing that looks for evidence of the parasite, including its oocysts. However, establishing a diagnosis can sometimes be difficult.
According to the CDC, multiple stool samples collected on different days may be necessary because the parasite may not be present in sufficient numbers in every sample.
How Do You Get Cyclospora?
People become infected with Cyclospora by consuming food or water contaminated with the parasite.
Cases are currently being reported across multiple states, including Connecticut, with Michigan experiencing a particularly large increase in cases.
The exact source of the current outbreak is still being investigated, but fresh produce has frequently been involved in previous Cyclospora outbreaks. Past outbreaks have been linked to foods such as berries, basil, cilantro, lettuce and salad mixes, green onions, and snow peas.
However, that does not mean these foods are the source of the current outbreak.
Another important detail is that Cyclospora is generally not thought to spread directly from one person to another. After the parasite is passed in stool, it requires time in the environment before becoming infectious.
Cyclospora Treatment
According to the CDC, most healthy people with Cyclospora infection will recover without treatment. However, untreated symptoms can last longer and may repeatedly improve and return.
The standard pharmaceutical treatment for cyclosporiasis is trimethoprim-sulfamethoxazole (TMP-SMX), commonly known by the brand name Bactrim.
Bactrim is a combination of two antimicrobial drugs and is generally taken for approximately 7–10 days, although the specific treatment plan will be determined by your prescribing doctor.

This can help to restore the overall health of your gastrointestinal system.
Can Natural Medicine Help With Cyclospora?
Natural medicines can modify the gastrointestinal environment, and many have antimicrobial properties. This means that they can act favorably in the management of gastrointestinal conditions.
There are none that I'm aware of which specifically target Cyclospora, but herbal medicines have been used traditionally in broader gastrointestinal and parasite protocols.
For those who prefer to avoid antibiotics, the following herbal options might be useful, but should be prescribed under the supervision of a naturopathic doctor.
Berberine
Berberine has broad antimicrobial activity and is commonly used in natural medicine for infectious or microbial causes of diarrhea. It may be considered in certain gastrointestinal protocols, depending on the suspected organism and your overall symptom picture.
Garlic
Garlic contains multiple different sulfur compounds which have documented antimicrobial and antiparasitic properties. Raw garlic and concentrated garlic preparations in particular can be highly useful.
An interesting fact about garlic is that it's been shown to kill a variety of microbes but also spares important beneficial ones like Lactobacillus and Bifidobacterium.
Oregano
Concentrated oregano oil contains compounds such as carvacrol and thymol that demonstrate broad antimicrobial activity. It's commonly included in natural protocols aimed at reducing unwanted intestinal organisms.
Wormwood
Wormwood has a long history of traditional use for intestinal worms and parasites. Its bitter compounds can also affect digestion, however, and it's generally better suited for short-term, supervised use.
Note: These herbs should not automatically be considered treatments for Cyclospora simply because Cyclospora is a parasite. Different parasites respond to different medicines, and concentrated antimicrobial herbs can strongly affect your gastrointestinal tract. They should be used carefully.
Homeopathy for Explosive Diarrhea
In my opinion, the top three homeopathic remedies to consider for explosive diarrhea are podophyllum, aloe, and croton.
Homeopathic medicines are prescribed differently because the remedy is selected according to the specific characteristics of your symptoms rather than the infectious organism.
Since the hallmark symptom of cyclosporiasis is explosive diarrhea, several common homeopathic medicines come to mind.
Podophyllum
Podophyllum is one of the classic homeopathic medicines associated with profuse, gushing, watery diarrhea. Your stool may be offensive, explosive, and accompanied by significant rumbling and urgency. Symptoms are often worse in the morning.
If your description is simply, "It just explodes out of me," Podophyllum may be helpful.
Aloe
Aloe is associated with tremendous urgency and the fearful feeling that you won't be able to hold the stool in.
There may be gurgling or spluttering diarrhea, and stool may accidentally pass while trying to pass gas. A sensation of rectal fullness and reduced control is common in the classic Aloe picture.
Croton Tiglium
Croton tiglium is often considered when diarrhea occurs suddenly and forcefully, particularly soon after eating or drinking. Your stool may be yellow, watery, and explosively expelled in one sudden gush.
It's important to understand that these homeopathic medicines are being discussed for their traditional symptom pictures. They have not been clinically established as treatments that eradicate Cyclospora infection.
When to Seek Medical Care
You should seek medical evaluation if your diarrhea is prolonged or severe, you are unable to maintain adequate fluid intake, you develop significant weakness or reduced urination, or you experience blood in the stool or severe abdominal pain.
Persistent watery diarrhea can cause significant fluid and electrolyte losses.
Older adults, young children, pregnant individuals, and people with compromised immune systems should seek medical care as soon as possible if they notice explosive diarrhea or any other symptoms of Cyclospora.
If you think you might have Cyclospora, be sure to mention the possibility to your healthcare provider. Specialized testing and potentially multiple stool samples may be necessary to establish the diagnosis.
Final Thoughts
Cyclosporiasis can produce prolonged or relapsing gastrointestinal symptoms, and identifying the actual cause of your diarrhea is important before deciding on treatment.
Natural medicines can support gastrointestinal health and symptom recovery, but confirmed Cyclospora infection requires appropriate medical evaluation and an organism-specific treatment discussion.
Be sure to speak with a qualified healthcare provider before initiating treatment for a suspected case of cyclosporiasis.
