There are many herbs and plants out there and some companies promote things regardless of doing a lot of research on them. I have researched the following plants/herbs/flowers and found that there are too many issues and side effects to be a desirable plant to grow or use.
Here is my list of plants that I am staying away from, I use Web MD as a reference to why it is on this list. Do your own research on any product you put in your body.
Echinacea is LIKELY SAFE for most people when taken by mouth in the short-term. Various liquid and solid forms of Echinacea have been used safely for up to 10 days. There are also some products, such as Echinaforce (A. Vogel Bioforce AG, Switzerland) that have been used safely for up to 6 months. Some side effects have been reported such as fever, nausea, vomiting, bad taste, stomach pain, diarrhea, sore throat, dry mouth, headache, numbness of the tongue, dizziness, difficulty sleeping, a disoriented feeling, and joint and muscle aches. In rare cases, echinacea has been reported to cause inflammation of the liver. Applying echinacea to the skin can cause redness, itchiness, or a rash. I dont want to be a rare case of liver failure.
Feverfew is LIKELY SAFE when taken by mouth appropriately in the short-term (up to four months). Side effects might include upset stomach, heartburn, diarrhea, constipation, bloating, flatulence, nausea, and vomiting. Other reported side effects include nervousness, dizziness, headache, trouble sleeping, joint stiffness, tiredness, menstrual changes, rash, pounding heart, and weight gain. The safety of feverfew beyond 4 months’ use has not been studied. Feverfew is POSSIBLY UNSAFE when fresh leave are chewed. Chewing unprocessed feverfew leaves can cause mouth sores; swelling of the mouth, tongue, and lips; and loss of taste. If making a tea from the leaves or flowers, small amounts of leaves can be swallowed or left in the mouth.
Hyssop is considered safe for most people in the amounts commonly found in foods and in medicinal amounts. However, do not use the oil product because it has caused seizures in some people. When heating in a tea, very small amounts of an oil like substance is a by product of heat being added to the leaves.
Cardamom is LIKELY SAFE when taken by mouth in amounts commonly found in food. It is POSSIBLY SAFE when taken by mouth in medicinal amounts, or when the vapor from the oil is breathed in, but the potential side effects of cardamom are not known. Do not take cardamom in amounts greater than those typically found in food if you have gallstones. The cardamom seed can trigger gallstone colic (spasmodic pain). Almost everyone who eats processed foods has gallstones. I know I do.
Valerian is LIKELY SAFE for most people when used in medicinal amounts short-term. Clinical research has reported safe use of valerian for medicinal purposes in over 12,000 people in studies lasting up to 28 days. The safety of long-term use is unknown. Some information suggests that valerian is POSSIBLY SAFE when taken by children for 4-8 weeks. Valerian can cause some side effects such as headache, stomach upset, mental dullness, excitability, uneasiness, heart disturbances, and even insomnia in some people. A few people feel sluggish in the morning after taking valerian, especially at higher doses. Some people experience dry mouth or vivid dreams. It’s best not to drive or operate dangerous machinery after taking valerian. The long-term safety of valerian is unknown. It might cause withdrawal symptoms when discontinued after long-term use. To avoid possible side effects when discontinuing valerian after long-term use, it’s best to reduce the dose slowly over a week or two before stopping completely. This is an addictive substance. I dont want to be a junkie.
