Solomon's Seal is the most useful remedy for treating injuries to the musculoskeletal system such as: broken bones, sprains, injured tendons and ligaments, tendonitis, arthritis, dryness in joints and "slipped"/herniated discs. Solomon's Seal can restore the correct tension to ligaments whether they need to be tightened or loosened. Valuable remedy for sports & activity related injuries, used either before resorting to or along with conventional surgical procedures. Can possibly help prevent the need for surgery or speed healing post surgery. 

Combinations: Wonderful as a base to build formulas upon. Combine with St. John’s Wort when nerves are involved. Combine with Mullein Root when there is a misalignment. Combine with Horsetail for healing bones & cartilage. Black Cohosh for dull, achy, inflammatory pain or whiplash. Goldenseal for disc injuries, Arnica (topically) for pain from injuries. Teasel for muscle injuries & tears. Blue Vervain if there's a lot of tension in the nape of the neck & upper shoulders (especially if it results from rigid, self imposed idealism). Yarrow if there is bruising, blood stagnation or, conversely, bleeding. Lobelia if there are severe muscle spasms. Combine with milky oat, fenugreek & burdock for Male infertility.  
Indications: Inflammation associated with heat and dryness. 
Essential Oil: N/A
Growing: A very hardy plant. Prefers light soil and a shady spot as it is a native of woodsy areas. In these conditions it will spread happily. You can collect the seeds in Fall and sow them immediately. They should happily germinate in the Spring. You can transplant or divide the roots. This can safely be done at any time but is a task best undertaken in the fall after the stalks have died back. 

Collection: Collect rhizomes (looks like a bone or knuckle) in fall. Tincture fresh in High proof alcohol such as ever clear or in rubbing alcohol (for external use). 
Here is a great video of Herbalist Jim McDonald demonstrating how to sustainably harvest Solomon Seal Root so that it keeps the plant in tact and has potential to actually help the plant spread. After, he also shows how you can tell the difference between True and False Solomon Seal:

Contraindications/Warnings: Seeds are toxic. Berries and leaves are knwon to cause nausea & vomiting. Be aware that Some say that False Solomon’s Seal and Bellflower can often be mistaken for True Solomon’s Seal. However when in flower it is clearly obvious the difference... 

                           True Solomon's Seal                                     False Solomon's Seal
                          (Polygonatum biflorum)                                 (Smilacina Racemosa) 

(Campanula rapunculoides)
I'll be honest with you here, I really don't see how this can be confused with either of the above, but some say otherwise so just in case ,here it is...)
